What is the solution of the following system?
[-3x – 2y = -12
19x + by = -9
(2.1)
no solution
(-2.-1)
infinitely many solutions

l.ln.lln.k.nkl

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
