The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
Answer:
2(x − 2)
Step-by-step explanation:
The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
The formula for the area of a rectangle = Length × Width
Area of the rectangle = 2x² + 8x - 24
Length = x + 6
We can find the width of the rectangle be factoring the Area
Hence, factorising
2x² + 8x - 24
= 2(x − 2)( x + 6)
Therefore, the Width of the rectangle =2(x − 2)
Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = 4
Step-by-step explanation:
Using the sine or cosine ratio.
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
x = 4
solve the system by substitution 3x-y=10 2x=y
Answer
X=10 and y=20
Step-by-step explanation:
since y=2x, you need to substitute that into the equation to get:
3x-(2x)=10
And evaluate:
x=10
Then substitute 10 into the equation: 2x=y:
2(10)=y
evaluate:
20=y
Now go back to the original equation to check your answer and substitute the values in:
3(10)-(20)=10
30-20=10
10=10

Classify the polynomial 30x
Answer:
C: monomial
Step-by-step explanation:
You need to classify the polynomial. But before we start, let's recall the basic classifications of polynomials:
Monomials
Binomials
Trinomials
Polynomials
What are monomials?
- expressions with only one term
What are binomials?
- expressions with two terms
What are trinomials?
- expressions with three terms
What are polynomials?
- expressions with four or more terms
30x is an expression with only one term, so it's a monomial.

y=38(0.29)^x
what is it
Answer:
Step-by-step explanation:
y=38(0.29)^x is an exponential function whose initial value (when x = 0) is 38. This function increases steadily from this value, due to the +(0.29) base of this exponential. As x grows increasingly large, the rate at which y is increasing drops steadily.
M(-5,2) and N(5,2) are the endpoints of the sedment MN on the cordinate plane what is the length of MN
Answer:
10 units
Step-by-step explanation:
Given data
The points are
M(-5,2) and N(5,2)
x1=-5
y1= 2
x2=5
y2= 2
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((5-(-5))²+(2-2)²)
d=√10²+0²
d=√100
d=10
Hence the distance is 10 units

Why would the velocity of a river affect its ability to erode sediment?
The power of a river to cause erosion and carry sediment depends on several factors. A rivers slope, volume of flow, and the shape of its stream bed all affect how fast the river flows and how much sediment it can erode. ... When a river slows down, it drops its sediment load.
The velocity of the river that impact the capability for eroding the sediment should be explained below.
Impact on the velocity of a river:In the case when the slope should be considered too gentle and here the velocity should be too slow for transporting the sediments that being supplied via weathering and erosion also the sediments should be piled up.
It rised the gradient that resulted the water to flow quickly that increased the erosion and transport due to which it decreased the gradient.

Answer:
k = 6
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here g(x) is the graph of f(x) shifted 6 units to the left
Then
g(x) = f(x + 6) → with k = 6

Consider the system of equations 3x + y = 10 and 6x – y = 17 . What is the value of the x-coordinate of its solution?
Answer:
x = 3
Step-by-step explanation:
These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.
3x + y = 10
6x - y = 17
____________
9x = 27
x = 27/9
x = 3
So, x- coordinate is 3
Answer: the answer should be x = 3

7. A triangle has side lengths of 9 and 5. Which of the following cannot be the length of the third side? *
The values less than 4 or greater than 14 cannot be the length of the third side
Which cannot be the length of the third side?From the question, we have the following parameters that can be used in our computation:
Side lengths of 9 and 5.
Represent the third length of the triangle with x
So, we have the following representation (using the triangle inequality theorem)
a + b ≥ c.
Substitute the known values in the above equation, so, we have the following representation
9 + 5 ≥ x
9 + x ≥ 5
5 + x ≥ 9
Evaluate the sum
14 ≥ x
x ≥ -4
x ≥ 4
So, we have
14 ≥ x
x ≥ 4
Combine
4 ≤ x ≤ 14
This means that values less than 4 or greater than 14 cannot be the length of the third side

The measure that cannot be the length of the third side is 14. Option
How to determine the lengthAn important rule to remember about triangles is called the third side rule:
Third side rule of triangles states that;
The length of the third side of a triangle is less than the sum of the lengths of the other two sides and greater than the (positive) difference of the lengths of the other two sides.
For this triangle, the length of the third side must be greater than
9- 5= 4
Also, the length of the third side must be less than
9 + 5 = 14
Hence, all the answers are possible except for answer D, which is equal to 14 but not less than 14.

Answer:
1) A
2) I
3) G
4) B
Step-by-step explanation:
1)
Bottom side: 7c - 1
Tall side: 6c + 2
P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2
P = 26c + 2
2)
P = 26c + 2
P = 26(5) + 2
P = 132
3)
P = 2(l + w)
P = 2(3d - 2 + 5d + 1)
P = 16d - 2
4)
P = 16d - 2
P = 16(3) - 2
P = 46
Special right triangles how do you solve them
The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.
In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means
(1) x = 48 √2
(2) 88 = √2 x → x = 88 / √2 = 44 √2
You could also set up trigonometric equations to solve for x in each case:
(1) cos(45°) = 48 / x → x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2
(2) cos(45°) = x / 88 → x = 88 cos(45°) = 88 (1 / √2) = 44 √2
