Lisa ordered 3 balls of yarn, for a total of 717.3 meters of yarn. how many meters of yarn did each ballon contain?

239.1 meters

Step-by-step explanation:

So we know Lisa ordered 3 balls and that the total yarn length between the three balls is 717.3 meters.

To figure out the length of ONE ball of YARN we must divide the amount for 3 balls of yarn by 3

= 239.1 meters per yarn ball

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
