Answer:
x = 3, the error is that the -2x should be added.

The -2x should be added to the left side.
3x - 7 = -2x + 8
3x + 2x = 8 + 7
5x = 15
x =3

Answer:
A = 708 mm^2
Step-by-step explanation:
![A=\frac{a+b}{2} h\\\\A=\frac{19+40}{2} *24\\\\A=\frac{59}{2} *24\\\\A= 708](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Ba%2Bb%7D%7B2%7D%20h%5C%5C%5C%5CA%3D%5Cfrac%7B19%2B40%7D%7B2%7D%20%2A24%5C%5C%5C%5CA%3D%5Cfrac%7B59%7D%7B2%7D%20%2A24%5C%5C%5C%5CA%3D%20708)
The area for a parallelogram is A=B•H
So the answer is 300cm^2 Bc you’d do 20•15=300
