A=xy and we are told y=12+x so

A=12x+x^2 and A=400 so

x^2+12x=400

x^2+12x-400=0

x=(-12±√1744)/2

x≈14.88

So the dimensions are approximately 14.88" by 26.88"

Solve for x: 3 over 4 x + 5 over 8 = 4x
vaieri [72.5K]

Step-by-step explanation:

3/4x + 5/8 = 4x/1

5/8 = 4x/1 - 3/4x

5/8 = 16x^2 - 3/4x

5/8 = 4x - 3/1

5/8 = 4x - 3

Cross multiply

8(4x - 3) = 5

32x - 24 = 5

32x = 5 + 24

32x = 29

X = 29/32
