Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping? x2(4x + 1) – 2(4x + 1) x2(4x – 1) + 2(4x – 1) 4x2(x + 2) – 1(x + 2) 4x2(x – 2) – 1(x – 2)
Answer:
see explanation
Step-by-step explanation:
Given
4x³ + x² - 8x - 2 ( factor the first/second and third/fourth terms )
= x²(4x + 1) - 2(4x + 1) ← first option on list
Finishing the factoring by factoring out (4x + 1) from each term
= (4x + 1)(x² - 2)

Using the properties of a kite, what is the measure of Angle X? 70° 90° 130° 140°
Answer:
70°
Step-by-step explanation:
Properties of a kite are:
a) They have two congruent sides
b) Their diagonal is perpendicular to each other.
c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same
We would be using the property of a kite that says "On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same" to solved this question.
In the diagram , the angles Z and X are opposite and congruent to one another. This means they are equal to each other.
Since angles Z= angle X
Let us call both of them angle a
Since a Kite is a Quadrilateral shape, the sum of angles in a Quadrilateral = 180°
Angle W = 90°
Angle Y = 130°
Angle X = a°
Angle Z = a°
Hence,
90° + 130° + a° + a° = 360°
220° + 2a° = 360°
2a° = 360° - 220°
2a° = 140°
a° = 140/2
a° = 70°
Therefore, from the calculation above, we can say that the measure of x = 70°
Answer:
70°
Step-by-step explanation:
Properties of a kite are:
a) They have two congruent sides
b) Their diagonal is perpendicular to each other.
c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same

Seth sold 20% of his baseball cards during week one. During week two, he bought 20% more cards than he had after week one. If he now has 10 fewer cards, how many cards did he have originally? (he had more than 100 cards originally.)
Answer:
250 cards
Step-by-step explanation:
Let the number of baseball cards he originally had be x.
He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:
x - (20/100 * x) = x - 0.2x = 0.8x
During week two he bought 20% more cards than he had after week one. This means that after week two, he had:
0.8x + (20/100 * 0.8x)
= 0.8x + (0.2 * 0.8x)
= 0.8x + 0.16x = 0.96x
He now has 10 fewer cards. This means that:
x - 10 = 0.96x
Collecting like terms:
x - 0.96x = 10
0.04x = 10
=> x = 10/0.04 = 250
He had 250 cards originally.

I am thinking of two numbers. The first is 5 more than the second. If you add the first number to three times the second number, you get 29. What are the two numbers?
Answer:
11 and 6 respectively
Step-by-step explanation:
1st number=x
2nd number=x-5
three times the second number=3(x-5)=3x-15
3x-15+x=29
put the liketerms together=3x+x=29+15
4x=44
(divide both sides by 4)x=11

in a survey of students 60% were in high school in 40% were in middle school of the high school students 30% had visited a foreign country if a survey of student is selected at random what is the probability that the student is in high school and has visited a foreign country?
Answer:
0.18
Step-by-step explanation:
Given: 60% students were in high school, 40% were in middle school and of the high school students, 30% had visited a foreign country
To find: probability that the student is in high school and has visited a foreign country
Solution:
Let x denotes total number of students
Number of students in high school = 60% of x = [tex]\frac{60}{100}x[/tex]
Number of students in middle school = 40% of x = [tex]\frac{40}{100}x[/tex]
Number of students who are in high school and have visited foreign country = 30% of Number of students in high school = [tex]\frac{30}{100}(\frac{60}{100})x=\frac{18}{100}x[/tex]
Probability that the student is in high school and has visited a foreign country = Number of students who are in high school and have visited foreign country/ Total number of students = [tex]\frac{\frac{18}{100}x}{x}=\frac{18}{100}=0.18[/tex]
Why does (-4 1/2)^2 = 20.25? Thank you please hurry!
Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25

The perimeter of the rectangle is 20 cm. One side is 6 cm long. What is the length of the missing side
Answer:
it is 4cm long
Step-by-step explanation:
You multiply 6 by 2 to get 12, then subtract 12 from 20 and get 8. Then you divide 8 by 2 to get 4. If you want to check it, you can add 6+6+4+4 to get 20
Answer: 4
Step-by-step explanation: the definition of a rectangle states that opposite sides of the rectangle are congruent. this means that there is 2 sides that measure 6cm. These two sides added together give us 12cm. By working backwards, we can subtract 12cm from the perimeter (20cm), this gives us 8cm. by diving that by 2 we can find the lenght of the missing sides, 4cm each.
find the axis of symmetry for this parabola y=-2x^2-4x-11
write your answer as an equation
Answer:
x = - 1
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = - 2x² - 4x - 11 ← is in standard form
with a = - 2 and b = - 4 , thus
x = - [tex]\frac{-4}{-4}[/tex] = - 1
x = - 1 is the equation of the axis of symmetry

Find the areas of the trapezoids. PLZ HELP!!!!
Answer:
Type 7.5 in the box!
Step-by-step explanation:
Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;
[tex]Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units[/tex]
Area = 7.5 square units
The area of the trapezoid is 7.5 square units.
To Find the Areas of TrapezoidsGiven: The length of base 1 = 1 unit,The length of base 2 = 4 units.
The length of height = 3 units.
Formula used and calculation:The area of the trapezoid
= (Average of the two bases) × Height
Putting all the values in the above formula, we get
The area of the trapezoid
= {(1 + 4)/2} × 3
= 7.5 square units.
Hence, the area of the trapezoid is 7.5 square units.

The graph of the function f(x) = 5 cos (2x) is a reflection over the x-axis of the graph of g(x) =
Answer:
[tex]g(x)=-5\cos (2x)[/tex]
Step-by-step explanation:
The given function is
[tex]f(x)=5\cos (2x)[/tex]
If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.
[tex]P(x,y)\Rightarrow P'(x,-y)[/tex]
If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is
[tex]g(x)=-f(x)[/tex]
Substituting the value of function f(x), we get
[tex]g(x)=-5\cos (2x)[/tex]
Therefore, the required function is [tex]g(x)=-5\cos (2x)[/tex].
