Could somebody give me step by step on how to do this please

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

One integer is 8 times another. if the product is 72, then find the integers
