First you rewrite all the expressions like this:
8x+4=(2x+12)+(2x+4)
then you solve and get:
x=3
to solve for AC, you have to solve 8x+4 by replacing x with 3
8x+4 would be rewritten as:
8(3)+4
AC=28
Answer:
twice the difference gives 2(difference). 7 = 14 20 = 40
Step-by-step explanation:
Answer:
x ≥ -7/2
Step-by-step explanation:
3 + 2x ≥ -4
Subtract 3 from each side
3-3 + 2x ≥ -4-3
2x ≥ -7
Divide each side by 2
2x/2 ≥ -7/2
x ≥ -7/2
Y=-x^2 is non linear due to the x being squared
The answer I think is 14 +x3
