First we will find the area of the wall

The height of the wall = 9 ft

Width of the wall = 10 ft

So area of wall = height*width

area= $9\times10=90$ square feet

And the rest painted area was = 46 square feet

Hence, total painted area = 90+46=136

So, a gallon of paint covered 136 square feet area.

Find the greatest common denomenator
factor the

w²-16=(w-4)(w+4)
w-4=w-4
w²+11w+28=(w+4)(w+7)

GCD=(w-4)(w+4)(w+7)

multiply by (w-4)(w+4)(w+7) to cancel fractions
