5(7) - 18 = 17. 4a. P = 3(7) = 21 in. 100 ÷ 21 = 4. 16. _. 21. 4 triangles b. ... GH. Exactly two sides are. , so △EGH is isosc. 7. EF = 3, EH = 8,. FH = 7.4 ... 47. Think: Each side has the same measure. Use the expression y + 10 for this ... 2(30) - 10 = 50. 24. ∠L. ∠P m∠L = m∠P x. 2 + 10 = 2 x. 2 + 1. 9 = x. 2 ... m∠BDA = 59°. 3.

Step-by-step explanation:

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
