Find the center and radius of the circle (x+1)2+y2=4

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?
