Complete the proof to show that abcd is a parallelogram. the slope of bc is . the slope of ad is . the slope of cd is . the slope of ba is . bc ∥ ad and cd ∥ ba because the . therefore, abcd is a parallelogram because both pairs of opposite sides are parallel.

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

its b

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

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
