Answer:
25
Step-by-step explanation:
a² + 7a + 7
a = 2
Plug in the value of 2 for every occurance of a.
(2)² + 7(2) + 7
First, solve the exponent.
4 + 7(2) + 7
Now, multiply.
4 + 14 + 7.
Add.
25
This is your answer.

One side of the back yard is usually the back side of the house.
But we won't worry about that ... we'll just go ahead and fence all
four sides, like you seem to have said.
Any rectangle has two sides that are the length and two sides that are the width.
So the distance around the back yard is
(14 + 14) + (12 + 12) = 52 meters.
(That's called the "perimeter" of the yard.)
If every meter of fence costs $9.00 , then 52 meters of fence will cost
(52) times ($9.00) = $468 . plus tax.

Answer:
Yes, they are equivalent.
Step-by-step explanation:
- To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.
- Apply the distributed property: 8 + 12
- 8 + 12 = 20
For second expression:
- 4(2) = 4 × 2 = 8
- 4(3) = 4 × 3 = 12
- Put them together: 8 + 12
- 8 + 12 = 20
Making a conclusion:
Because they both have the same answer, they are equivalent expressions.
I hope this helps!
