Jon is replacing a treated wood walkway with rectangular concrete slabs 24 inches by 16 inches. Each slab is 2 ½ inches thick. The walkway is 48 inches wide and 20 feet long. How many concrete slabs will be required to complete the project if each row contains 2 slabs?

it goes right

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

the graph g(x) is f(x) translated 7 units in the negative y direction and translated 2 units in the negative x direction
