Answer:
See below:
Step-by-step explanation:
We can first setup an equation by doing the following:
![4(2-x) = 3(x+1)\\8-4x=3x+3\\8-7x=3\\-7x=3-8\\-7x=-5\\x=-5/-7 (5/7)](https://tex.z-dn.net/?f=4%282-x%29%20%3D%203%28x%2B1%29%5C%5C8-4x%3D3x%2B3%5C%5C8-7x%3D3%5C%5C-7x%3D3-8%5C%5C-7x%3D-5%5C%5Cx%3D-5%2F-7%20%20%285%2F7%29)

Answer:
D. -12s squared + 11st - 2t squared
Step-by-step explanation:
FOIL:
-3s(4s) - 3s(-t) + 2t(4s) + 2t(-t)
- 12s² + 3st + 8st - 2t²
Simplify.
- 12s² + 11st - 2t²

Answer:
B = 70
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
40 + 2x-30 + x+20 = 180
Combine like terms
3x + 30 = 180
Subtract 30 from each side
3x+30-30 = 180-30
3x = 150
Divide by 3
3x/3 =150/3
x = 50
We want to find angle B
B = 2x-30
=2(50) - 30
= 100 - 30
= 70
