101
(2,4)
10
10
10
A. y-2 = 3(x-4)
B. y - 4 = 3 (x - 2)
O c. y - 4 = 3(x + 2)
D. y- 1 = 3(x-13)

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

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!

sas (side angle side)

aa(angle angle)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
