What is the first step in solving the quadratic equation x^2-40=0
a. taking the square root of both side of the equation
b. adding 40 to both sides of the equation
c. squaring both sides of the equation
d. subtracing 40 from both sides of the equation

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

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.
