chandler can mow 2 lawns per hour. if l represents lawns and h represents hours, which of the following equations represent this rate relationship?

h = × l
l = × h
l = 2 × h
h = 2 × l

L = 2 * H

Step-by-step explanation:

He can mow 2 lawns per hour.

So we know that if it is an hour he mowed 2 lawns. If it was 2 hours he mowed four lawns and so forth.

Therefore, we now have 2 * H

The answer to this equation will be L, the amount of lawns.

Leaving us with the L = 2 * H

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
