Can someone help me with this ?

SSS --> SAS --> AAS --> SAS --> HL --> SSS --> ASA --> AAS --> HL --> SAS --> HL

Step-by-step explanation:

To do this problem, look at the angles that are marked congruent as well as the sides. Then look at the order that the angles and sides are placed. If it is SSS, then that means three sides are marked congruent. SAS means the order of the side and angles would be side then angles then another side. AAS means angle then angle then side. HL is when you have a right triangle and one of the legs are congruent as well as the hypotenuse. ASA means an angle then side then another angle.

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
