Let's let l represent the length of the rectangle (in inches), let w represent the width of the rectangle, let p represent the perimeter of the rectangle (in inches), and let A represent the area of the rectangle (in square inches). Write a formula that determines the perimeter p of the rectangle given its width w and length l .

p = 2(l + w)

Step-by-step explanation:

A rectangle has two lengths and two widths. The formula for the perimeter of a rectangle is obtained by adding all the four sides of the rectangle.

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

p = 2l + 2w

2 is a common factor of both terms on the right hand side

Factorizing 2l + 2w

p = 2(l + w)

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
