I need this awnsered

6x + 40 = 88
You must multiply the length by the width to find the area of a rectangle. The length is 8 and the width is [tex]\frac{3}{4} x[/tex] + 5.
Multiplying these is as follows: 8([tex]\frac{3}{4} x[/tex] + 5)
You have to multiply the 8 by the [tex]\frac{3}{4} x[/tex] and then the 8 by the 5, and add these together.
8 * [tex]\frac{3}{4} x[/tex] = 6x
8 * 5 = 40
The equation is therefore 6x + 40 = 88.
