Answer:
B. 4x^2=28x-112=0.
Step-by-step explanation:
Using area=length*width, 160=(2x+8)(2x+6).
Expanding, (2x+8)(2x+6)=4x^2+16x+12x+48.
Setting this equal to 160, 160=4x^2+28x+48, or 4x^2+28x-112=0.
Answer:
m = -2
Step-by-step explanation:
<em>Distribute first.</em>
24 = -6(m+1) + 18
24 = -6m - 6 + 18
<em>Then you combine like terms.</em>
24= -6m + 12
<em>Then you still combine like terms. You subtract 12 from each side.</em>
24 = -6m + 12
-12 - 12
12= -6m
<em>Then divide by -6 to isolate the variable.</em>
12 = -6m
/-6 /-6
-2 = m
