Step-by-step explanation:
a=4 so 3a becomes 3x4.
3x4=12
12+6c^2
C=2 so 6c^2 becomes (6x2)^2
6x2=12 and 12x12 because of the exponent.
12x12=144
12+144=156

Answer: 3.50p + 5.50p +6 = 51; 61
Answer: 5 people
Step-by-step explanation:
For this word problem, we can use the description in the problem to construct an equation. Let's use x for number of people.
3.5x+5.5x+6=51 [combine like terms]
9x+6=51 [subtract both sides by 6]
9x=45 [divide both sides by 9]
x=5

Which two numbers of the given data set have the same absolute value? Explain your answer in full sentences.
-5, 5, -3, 8
pls help. ;)
Answer:
The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)
Step-by-step explanation:
Answer: the two numbers that have the same absolute value is -5, and 5.
Step-by-step explanation:
Absolute will just make any negatives to positive.
So, the absolute value of -5 is 5, or the absolute value of -3, is 3.
If it's already positive, then nothing happens; it stays the same
So, the absolute value of 8 is 8, nothing is changed.

Answer: A,D
Step-by-step explanation:
I f m ∠ P i s t h r e e l e s s t h a n t w i c e t h e m e a s u r e o f ∠ Q , a n d ∠ P a n d ∠ Q a r e s u p p l e m e n t a r y a n g l e s , f i n d t h e m ∠ P .
Answer:
The value of angle P is 119 degrees
Step-by-step explanation:
When two angles are supplementary, it means that they add up to be 180 degrees. For example, if we have two angles only on a straight line, then both angles are supplementary angles.
Now, the information we have from the question is that angle P is three less than twice the measure of Q.
What this mean is that if Q is x, then P is 2x-3
So let’s add both to equal 180 since they are supplementary;
x + 2x -3 = 180
3x -3 = 180
3x = 180 + 3
3x = 183
x = 183/3
x = 61
This is the value of Q;
The value of P which we are asked to look for is 2x -3 = 2(61) -3 = 122 -3 = 119 degrees

F(x)=-2x^2 -5x+1
H(x)=3(x+3)^2-11
H(f(-1))=?
A.132
B. 136
C.140
D.144
Answer:
B
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=-2x^2-5x+1\text{ and } h(x)=3(x+3)^2-11[/tex]
And we want to find:
[tex]h(f(-1))[/tex]
So, find f(-1) first. Substitute -1 into f(x):
[tex]f(-1)=-2(-1)^2-5(-1)+1[/tex]
Square:
[tex]f(-1)=-2(1)-5(-1)+1[/tex]
Multiply:
[tex]f(-1)=-2+5+1[/tex]
Add:
[tex]f(-1)=4[/tex]
Now, substitute this into h(f(-1)):
[tex]h(f(-1))=h(4)[/tex]
So, substitute 4 into h(x):
[tex]h(4)=3(4+3)^2-11[/tex]
Add:
[tex]h(4)=3(7)^2-11[/tex]
Square:
[tex]h(4)=3(49)-11[/tex]
Multiply:
[tex]h(4)=147-11[/tex]
Subtract:
[tex]h(4)=136[/tex]
So, our answer is B.
