Answer:
A.) 10 years old
Step-by-step explanation:
Sam: John - 14
S = J - 14

10 x 24 = 240
Answer:
(x - 6)² + (y - 7)² = 4
Step-by-step explanation:
Equation of circle: (x - h)² + (y - k)² = r²
Given center(h,k) = (6,7)
h = 6
k = 7
Dimeter = 4 --
radius, r =
= 2
(x - h)² + (y - k)² = r²
(x - 6)² + (y - 7)² = 2²
(x - 6)² + (y - 7)² = 4
Solution
-3b + 11 = -18 + 8b
-3b - 8b = -18 - 11
-11b = -29
b = 29/11
