= 2ab + 4a + 6 - 6
= 2ab + 4a
you can factor this to 2a(b + 2)
I believe the answer is C -4
Edit . . . I might have been wrong haha thinking backwards

Answer:
Step-by-step explanation:
So, the point of this is to make x the only thing on one side, so we can see what x is!
Okay so first subtract 8 on both sides...
5x= 25
Now we need to divide on both sides!
That equals...
x=5
So now we know that x=5!
Hope this helped!! :D

Answer:
$3
Step-by-step explanation:
let the cost of apple pie be
and the cost of chocolate pie be
.
We then express the situation as:
![2y+4x=38\ \ \ \ \ \ ...eqtn1\\\\14y+12x=138\ \ \ \....eqtn2](https://tex.z-dn.net/?f=2y%2B4x%3D38%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20...eqtn1%5C%5C%5C%5C14y%2B12x%3D138%5C%20%5C%20%5C%20%20%5C....eqtn2)
#Make y the subject of the formula in equation 1 then substitute in 2:
![2y=38-4x\\y=19-2x\\\\\therefore 14(19-2x)+12x=138\\\ \ 266-28x+12x=138\\\ \ 128=16x\\x=8\\\\y=19-2\times8=3](https://tex.z-dn.net/?f=2y%3D38-4x%5C%5Cy%3D19-2x%5C%5C%5C%5C%5Ctherefore%2014%2819-2x%29%2B12x%3D138%5C%5C%5C%20%5C%20266-28x%2B12x%3D138%5C%5C%5C%20%5C%20128%3D16x%5C%5Cx%3D8%5C%5C%5C%5Cy%3D19-2%5Ctimes8%3D3)
Hence, the cost of a chocolate pie is $3
