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.

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

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
