Rebecca has an old drafting table in her garage. She wants to give it to her nephew Devon as a graduation gift. She purchased product from Home Depot in order to place a nice coat of paint and finish. The paint cost her $2.00 per square foot and and the stain cost $14.00. Given the dimensions of the table, how much did it cost Rebecca to paint and finish?

The rectangle is 4 feet by 5 feet. The base of the triangle is 2 feet.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
