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

The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
Answer:
∠EGF = 1/2( 180 - 50) = 1/2(130) = 65
∠CGF = 180 - 65 = 115.

Answer:
35d+ 32 > 25d+68
Step-by-step explanation:
Plan A: $35 a day plus a fee of $32
35d+ 32
Plan B: $25 a day plus a fee of $68
25d+68
We want to know when A costs more than B
35d+ 32 > 25d+68
