Answer:
x=-2,-4 is your answer
x²+6x+8=0
doing middle term factorization
x²+4x+2x+8=0
x(x+4)+2(x+4)=0
(x+4)(x+2)=0
either
x=-4
or
x=-2
Answer:
Step-by-step explanation:
y = a|x-h| + k
(h,k) is the vertex
There's no standard formula for absolute values. I just made it up as an example, pretty much.
Since a is negative, the function opens downward.
h = -2, k = 0, so the vertex is at (-2,0)
We are given
area of sphere is 200.96cm^2
it means that we are given surface area
so, we can use surface area formula

where S is surface area
r is radius
so, firstly we need to find radius or r

we can solve for r

now, we can find volume

we can plug r

now, we can find volume
