Answer:
-5x^2 - 25x + 18
Step-by-step explanation:
-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 ) ( original equation )
-3x^2 - 24x + x + 18 - 2x - 2x^2 ( distribute )
-3x^2 - 2x^2 - 24x + x - 2x + 18 ( order them based on the variables . )
( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 ) ( just separated them not a part of solving !! )
-5x^2 - 25x + 18 ( solved , and the answer :) )
Hope its helps !!!

Answer:
4 5/6
4×5=20+6=
26/6
26÷2=13
6÷2=3
The vertex form:
(h,k) - the coordinates of the vertex
The coordinates of the vertex are
(-4,13).
0.03 x 0.6
= (3 x 6) / 1000
= 18 / 1000
0.018
