Determine whether the two triangles are congruent. If they are congruent, state by what theorem (SSS, SAS, or ASA) they are congruent. Let a = 111, c = 39, x = 7, d = 111, f = 39, and y = 7. a. Yes, the two triangles are congruent by the SSS Theorem.
b. Yes, the two triangles are congruent by the SAS Theorem.
c. Yes, the two triangles are congruent by the ASA Theorem.
d. No, the two triangles are not congruent.

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

im sorry but no. i just need to answer for 50 poonts oof

hiking down a winding trail.

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

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
