Amechanic has a radiator hose that measures 32 feet long. it needs to be cut into pieces equaling 5 feet 3 inches. how many whole pieces can it be cut into? 4 pieces 6 pieces 7 pieces 8 pieces hint 1 foot = 12 inches

It can be cut in to 6 whole pieces.

Step-by-step explanation:

A mechanic has a radiator hose that measures 32 feet long.

It needs to be cut into pieces equaling 5 feet 3 inches.

1 foot = 12 inches

32 feet = 12 × 32 = 384 inches

5 feet 3 inches = (12 × 5) + 3 = 63 inches

Since the length of radiator hose = 384 inches

it need to be cut into 63 inches pieces.

The total number of pieces would be cut =

                                                                   = 6.09 ≈ 6 pieces

It can be cut in to 6 whole pieces.

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
