Answer:
x^2+2x+2
Step-by-step explanation:
(x+1)(x+1) multiply out
Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer: 
Step-by-step explanation:
Vertical Angles states that 9x+27=117
Supplementary Angles states that 117+z=180

The answer is x=57
its this because x+17=74 you subtract 17 from each side getting x=57
Answer:
The equation is, y = 9x + 3.25 and spending $39.25 will give him 4 classes.
