1-If a +b = -2, then (a + b)3 = A) 4
B) 0
C) -4
D) -8

2-For what value of n is (n – 4)² = (n +4)²?

sine

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
