Joseph is given the formula for the perimeter of a rectangle. the first step in solving for the variable l in the equation p=2l +2w is to:

step-by-step explanation:

first, let's move the 2w to the other side by subtracting 2w from both sides of the equation. what ever operation we do to one side we also have to do to the other side to keep things equal:

p - 2w = 2l + 2w - 2w

since 2w - 2w = 0, it reduces to:

p - 2w = 2l

now we just need to get rid of the factor of 2 that multiplies the l. we undo multiplication with division, so divide both sides by 2:

(p-2w)/2 = 2l/2

since 2l/2 = l, we have:

(p-2w)/2 = l is the final answer

the answer is 8/21

hope this

hey there : ) your answer would be a.
