Glenda is incorrect. shes wrong because she wrote 4/10 thats close to 1/2 but its not one half
<span>9x-4=7-2x <em>/+2x
</em><em />11x-4=7 <em>/+4
</em><em />11x=11 <em>/:11
</em>x=1<em>

Hello from MrBillDoesMath!
Answer:

Discussion:
f(x) = 3x2 - 2x + 5
Substitute x = -2 in f(x) above to get
f(-2) =
3 (-2)^2 - 2(-2) + 5 = => (-2)^2 = (-2) * (-2) = +4, -2(-2) + + 4
3*4 + 4 + 5 =
12 + 4 + 5 =

Thank you,

The shape of the fire departments are rectangles of coordinates 3 by 2.
There are only two possible 3 by 2 rectangles that we can draw, as shown in the picture:
I) C(1, 1), D(4, 1), or II) C(1, 5), D(4, 5).
From the available choices, we see that the answer is only a.
Answer: a
