Answer:
B) 7v^3-15v^2-17v-3
Step-by-step explanation:
(v-3)(7v^2+6v+1)
7v^3+6v^2+v-21v^2-18v-3
7v^3+6v^2-21v^2+v-18v-3
7v^3-15v^2-17v-3
If it's add you subtract if it's subtract you add
It is incorrect because when you times a negative by a positive. It is a negative number.
Answer:
x = 21
Step-by-step explanation:
Based on the inscribed angle theorem, we would have:
120° = 2(3x - 3)°
Solve for x
120 = 2*3x - 2*3
120 = 6x - 6
Add 6 to both sides
120 + 6 = 6x
126 = 6x
Divide both sides by 6
126/6 = x
21 = x
x = 21
