One side of a rectangle has length a. Another side has length b. How can you
express the perimeter of the rectangle as a
polynomial?

2a + 2b

Step-by-step explanation:

Since it's a rectangle, there are two sides with the length "a," and two sides with the length "b."

Let's say a = 4, and b = 8

2(4) + 2(8)

8 + 16 = 24

We can prove this is correct, by adding 4 + 4 + 8 + 8 together, since you're looking for the perimeter

I hope this helped :)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
