Answer:
[tex]\left(a+4\right)\left(a-5\right)[/tex]
Step-by-step explanation:
Break the expression into groups.
=(a^2+4a)+(−5a−20)
Factor out a from a2+4a: a(a+4)
Factor out −5 from −5a−20: −5(a+4)
=a(a+4)−5(a+4)

find quotient and reminder of 4x³-12x²+15x-5÷2x-1
Answer:
The quotient is 2x² - 5x + 5, while the remainder is 0
Step-by-step explanation:
Given polynomial function;
4x³-12x²+15x-5 and a factor of 2x - 1
The quotient and remainder of the polynomial is calculated using the long division method;
2x² - 5x + 5
------------------------
2x - 1 √ 4x³-12x²+15x-5
- (4x³ - 2x²)
----------------------------
-10x² + 15x - 5
- ( -10x² + 5x)
--------------------------------
10x - 5
- (10x - 5)
-----------------------------------------
0
Therefore, the quotient is 2x² - 5x + 5, while the remainder is 0.
Your scores on the first 4 tests in Algebra were 85, 80, 90, and 93. What do you need to make on the 5th test to have a 90 average in the class?
Answer:
you would have to get a 100 on your fifth test
Step-by-step explanation:
because between your first 4 tests, the average is only 87 something but when you add 100 to that, the average turns to 89.6 which when rounded becomes 90.

3/7 of the students in a school are in sixth grade. How many students are in the school if 63 of them are sixth graders?
Answer:
There are 147 students in the school.
Step-by-step explanation:
3/7 of the students are in sixth grade, 63 students are in the sixth grade.
take 63 and divide it by the numerator, 3, you get 21.
You now multiply the fraction by 21 to get the full number of students in the school.
3 * 21 = 63, 7 * 21 = 147
So 63 sixth graders out of 147 total students in the school.

Step-by-step explanation:
what is the median of this data set?
16,21,28,30,34,45,58,60
Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

If h(x) = 5x - 3 and j(x) = -2x, solve hlj(2)] and select the correct answer below. (1 point)
17
23
-17
-23
Answer:
-23
Step-by-step explanation:
We are given the functions;
h(x) = 5x - 3 and j(x) = -2x
Now, we want to find h[j(2)]
j(2) = -2(2)
j(2) = -4
Thus;
h(-4) = 5(-4) - 3
h(-4) = -20 - 3
h(-4) = - 23

If the signal had four circular lights, each having the same diameter, what would the total area of all four lights be?
Answer:
The answer is "[tex]153.86 \ in^2[/tex]"
Step-by-step explanation:
The circular light which fits around rather than is sufficiently large for fire a camera is indeed a ring light. The ring light provides light with very little darkness, as the bright light is very close to a lens's vertical system. It's also usually called glamour or brightness of beauty.
Let's Each light surface area has [tex]38.465\ in^2[/tex].
Therefore, the total area of four lights is [tex]38.465 \times 4= 153.86\ in^2[/tex].

Brian needs to find the value of a number, a, so that when (x^2+3x) is added to the binomial (3x^2+ax), the sum simplifies to 4x^2+12x. What is the value of a?
Answer:
a = 9
Step-by-step explanation:
First we need to add (x^2+3x) to (3x^2+ax),
(x^2+3x)+(3x^2+ax)
Expand
= x^2+3x+3x^2+ax
Collect the like terms
= x^2+3x^2+3x+ax
= 4x^2 + 3x + ax
= 4x^2+(3+a)x
Equate the solution to 4x^2+12x
4x^2+(3+a)x = 4x^2+12x
Comparing the like terms on both sides
(3+a)x =12x
3 + a = 12
a = 12 - 3
a = 9
Hence the value of a is 9
In the system below, what is the value of k if x = 4? What is the solution to the system?
6x + 8y = k
x + y = 1
The system's solution is (xy, y) = and the k-value is 0. (4, -3).
What does the word "value" mean?Something that someone values are referred to as values. The things that only a person or a company considers "important" are, in other words, their values. Examples include valor, integrity, freedom, and inventiveness.
How do worth and value differ?Value includes both the material and emotional cost of that possession. Only the item's monetary price may be considered its worth. An object's value often remains constant, although it might change based on the person and how much the thing means to them personally.
If [tex]x = 4[/tex], then we can substitute [tex]4[/tex] for [tex]x[/tex] in the second equation to get:
[tex]4 + y = 1[/tex]
Subtracting [tex]4[/tex] from both sides, we get:
[tex]y = -3[/tex]
Now we substitute [tex]x = 4[/tex] and [tex]y = -3[/tex] into the first equation to solve for [tex]k[/tex]:
[tex]6x + 8y = k[/tex]
[tex]6(4) + 8(-3) = k[/tex]
[tex]24 - 24 = k[/tex]
[tex]k = 0[/tex]
Therefore, the value of [tex]k[/tex] is [tex]0[/tex], and the solution to the system is [tex](x, y) = (4, -3)[/tex]

4) H
Step-by-step explanation:
1)
P = a + b + c + d
P = 7x + 8 + 7x + 8 + 9x + 4 + 12x - 2
P = 35x + 18
2)
P = 4a
P = 4(4x - 8)
P = 16x - 32
3)
P = 5a
P = 5(2x - 4)
P = 10x - 20

P = 4a
P = 4(7x + 2)
P = 28x + 8
Nic sells advertising packages for a radio station. The company pays him $ 150 $150 per week and they also pay him $ 75 $75 for every package he sells. His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275 $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?
Answer:
15 Packages
Step-by-step explanation:
Let number of packages = x
For Nic
Nic sells advertising packages for a radio station. The company pays him $ 150 per week and they also pay him $ 75 for every package he sells.
Equation =
150 + 75x
His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275per week.
We solve by equating
150 + 75x = 1275
75x = 1275 - 150
75x = 1125
x = 1125/75
x = 15 Packages
