X²+y² =(Radius)²
x²+y² =10². So the radius is 10
x^2 - 4
------------------------------
x + 7 | x^3 + 7x^2 - 4x - 28
x^3 + 7x^2
------------------
0 - 4x - 28
-4x - 28
-------------
0
Now we know that
x^3 + 7x^2 - 4x - 28 = (x^2 - 4)(x + 7)
x^2 - 4 can be factored since it is the difference of two squares.
x^2 - 4 = (x + 2)(x - 2)
The complete factoring is:
x^3 + 7x^2 - 4x - 28 = (x +2)(x - 2)(x + 7)
Answer:
A
Step-by-step explanation:
3(5+x)
3(5)+3(x)
15+3x
Answer:
<h2>y = -3x + 3</h2>
Step-by-step explanation:


-4x + 4 = 6
x = -.5
2x + 10 = 50
x = 20
-3x - 14 = -5
x = -3
2/3x + 2 = 5
x = 4.5
