Answer:

Step-by-step explanation:
We are given zeros as x=-4, x=-2
so, we can set up function as

Vertex is at (-1,3)
It means that graph passes through point (-1,3)
so, we can plug x=-1 and f(x)=3
and then we can solve for 'a'

we get

now, we can plug it back
and we get

now, we can simplify it

Because otherwise the two circles you build wouldn't have any intersection!
You have to draw two circles, centered at the endpoints of the segment, and connect their intersection.
If the radii are less than half the length of the circle, the circles will have no interserction.
I don’t understand what your asking are you trying to find the cube of a certain number?
Answer:
A=30
Step-by-step explanation:
Set your equation up as following:
180=90+(x+37)+(x+67)
180=90+37+67+2x
180-90-37-67=2x
-14=2x
-14/2=x
-7=x
Angle A = x+37
A=-7+37
A=30
