The width of a rectangle is 12 units. can the perimeter x of the rectangle can be 60 units when its length y is 18 units?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
