(-2,-6) because when factored the values of x are -2,-6
<span>x² + 8x + 12 = 0
(x+6)(x+2)=0
x+6=0
----> x=-6
x+2=0
----> x=-2</span>
Answer:
1342 feet
Step-by-step explanation:
Answer: 7x + 261
Step-by-step explanation:
(5x + 252 + x + 5) + (x + 4)
5x + 252 + x + 5 + x + 4 (get rid of parenthesis)
7x + 261 (combine like terms)
Answer:
V = 301 ft^3
Step-by-step explanation:
The volume of a cone is given by
V =1/3 pi r^2 h
We know pi = 3.14 r =6 and
We need to determine h
We can find h from the Pythagorean theorem where 6 is a leg and 10 is the hypotenuse
h^2 +6^2 = 10^2
h^2 +36 = 100
h^2 = 64
Taking the square root of each side
h = 8
V =1/3 pi r^2 h
V = 1/3 (3.14) (6)^2 * 8
V = 301.44 ft^3
Rounding to the nearest cubic foot
V = 301 ft^3
Answer:
Step-by-step explanation:
discriminant = (-13)² - 4·2·15 = 49
discriminant > 0 so there are two real roots
