Which statements are always true regarding the diagr. check all that apply. m25+ m23 = m 21 m23+ m 24+ m25 = 180° m25+ m26 =180° m2 + m 23 = m 26 m2 2 + m 23+ m 25 = 180° multiple choice btw

the answer is d

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
