-3.2, -2.6, -2, -1, 3, 4.55, 8, 8.2, 10, 25, 77

Step-by-step explanation:

Since negative numbers are smaller than positive numbers, those would be ordered first. A negative number that has the greater absolute value (for example the absolute value of -3 is 3) is the number that is smaller. After that, you order every other number as it would appear when you count.

-6 is the correct option from the above given options

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
