#14: mr. mcbride ordered 6 cheese pizzas and 7 pepperoni pizzas and
paid $153.50 for his son's birthday party. he realized he was going to
run out of pizza and made a second order. this time, he ordered 2
cheese and 2 pepperoni pizzas and paid $47.00. what is the cost of one
pepperoni pizza? *
your answer

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the square root of what number? if you add that, then someone will probably answer the question.

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
