Find the perimeter of the rectangle
10x - 3
2x + 6

Step-by-step explanation:

We know that the perimeter of a rectangle's formula is , where l is the length and w is the width - p is the perimeter. We know the length and width, so we can substitute into the equation.

We can now combine like terms to get .

Hope this helped!

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
