Solve for x:
x^2 + 10 x + 12 = 36
36 = 36:
x^2 + 10 x + 12 = 36
Subtract 12 from both sides:
x^2 + 10 x = 24
Add 25 to both sides:
x^2 + 10 x + 25 = 49
Write the left hand side as a square:
(x + 5)^2 = 49
Take the square root of both sides:
x + 5 = 7 or x + 5 = -7
Subtract 5 from both sides:
x = 2 or x + 5 = -7
Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.
Answer: The answer is $4.20

Step-by-step explanation:
Answer:
d. f opens upward with a y-intercept at (0, 2); h opens downward with a y-intercept at (0, -2)
<span>1.)what is the factored form of 72x-9
= 9(8x -1)
2.) expand: -3(-4y-9x)
= 12y + 27x
3.)simplify: 6(-5y+3)-25
= -30y + 18 -25
= -30y - 7
4.) write an equivalent expression for 15m-3
= 3(5m-1)
5.) simplify: 3/4 (16g-28h)-10h
= 12g - 21h - 10h
= 12g - 31h</span>
