Kim is making birthday cards. Each card is rectangular with an area of 36 square inches, and the length is 5 inches more than the width. Find the length and width of her cards. If x represents the width of each card, select all of the equations that could be used to solve this problem.

Respuesta :

Answer:

Step-by-step explanation:

So the Area = 36 in^2

Area = l * w

l = w +5

Area = (w+5)*w

36 = w^2+5w

w^2+5w-36 = 0

Use the quadratic formula

w=4 in

And if x = width, than x= 4in
