Answer:
x=0,-2
Step-by-step explanation:
Solve the solution by equaling them to each other and solve for x.
x^2+5x+6=3x+6
x^2+5x-3x+6-6=0
x^2+2x=0 (factor out one x)
x(x+2)=0
x has two solutions since there are two options of solving.
1. x=0/(x+2)
x=0
2. x+2=0/x
x+2=0
x=-2
Answer:
.000105
Step-by-step explanation:
How I got the answer was when I multiplied them together I got 00105, but you have 6 decimal spots, so the answer is .000105.
Y=-x+4
y=-2x-4
(
for elimination subtract as is
y=-x+4
y=-2x-4
-------------
0 = 1 x + 8
so
x = -8
then get y = 8+4 = 12)
Volume of a sphere: (4/3)πr³
r=radius=9 in
Volume=(4/3)*π*(9 in)³=972π cubic inches≈3053.63 in³
answer: D) 972π cubic inches (3053.63 in³ is correct)
