I am using the laws:
1)

2)

3)

an x is a base - the law is valid if the bases are the same number!
The solution in attachment :)
X=32 because both equations are equal to 180 degrees (3x+22°+x+30°=180) just solve that equation and you’ll get your answer
Answer:
12
+ 29x - 14
Step-by-step explanation:
(3x+2)(4x-7)
Multiply out 3x first then 2
(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)
12
- (- 21x) + 8x + ( -14)
12
+ 21x + 8x - 14 Combine like terms
12
+ 29x - 14
Line the decimals up and add like you normally would.But don't forget to put your decimal in your answer
