Answer:
The circle is centered at (-8,3) and has a diameter of 20 units
Step-by-step explanation:
we know that
The equation of a circle in center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
so
The center is the point (-8,3)
The radius is 
so
The diameter is two times the radius
therefore
The circle is centered at (-8,3) and has a diameter of 20 units
6x²+x-12
the first thing we need to do is find 2 numbers that add up to equal the middle term (1) but multiply together to get a product of -72 (-12*6)
two numbers that would fit this is 9 and -8
so now we placed 9x and -8x in place of the middle term
6x²+9x-8x-12
now we look for whats common between the first two numbers and divide them out
6x²+9x = 3x(2x+3)
now we do the same with the last two numbers
-8x-12 = -4(2x+3)
notice how the numbers in brackets are the same (2x+3)
we will keep (2x+3) and then combine the numbers on the outside
once we do that you should get an answer of
(3x-4)(2x+3)
hope this helped!
Answer:
b
Step-by-step explanation:
a x (b + c) = (a x b) + (a x c)
The slope for this equation is x=3
