The equation of a circle whose center is at (4, 0) and radius is length 2√(3) is (x - 4)² + y² = 2√3
(x - 4)² + y² = 12
(x + 4)² + y² = 12

B. (x - 4)² + y² = 12

Step-by-step explanation:

Rewrite in standard form to find the center (h,k) and radius r.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
