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 :)

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
