In a survey 46 people, which was 20% of those surveyed, chose red as their favorite color. how many people were surveyed?

ok well you find the answer you divide 46 by 0.20 and you come out with the answer 9.2 and you round down to 9

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

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
