Answer:
c
Step-by-step explanation:
1.) move all terms that are not x to the right side.of the inequalities.
10+x≤20 <u>4x</u>≥<u>-24</u>
-10 -10 4 4
x≤10 x≥-6
2.) combine the two equations to make -6≤x≤10
(2x-3)/(2(x+2))
x cannot equal -2

Step-by-step explanation:
answer: y= 2x^2+2x-4
steps:
y= (2x+4)(x-1)
*FOIL method* y= (2x^2-2x+4x-4)
*simplify* y= 2x^2+2x-4
