Answer:
x=35
Step-by-step explanation:
2x+15+2x-10+x=180
combine factors
5x+5=180
-5 from both sides
5x=175
divide 175/5x
x=35
Answer:
(2, -16).
Step-by-step explanation:
(x - 6)(x + 2)
Convert to vertex form:
Expanding the parentheses we have:
x^2 + 2x - 6x - 12
= x^2 - 4x - 12
Completing the square:
= (x - 2)^2 - 4 - 12
= (x - 2)^2 - 16
So the vertex is (2, -16),
