During a drought, a pond's fish population decreased by 3
for every meter drop in the pond's water level. At that rate,
how many fish died once the water level dropped 4 meters?

Lines b and c are parallel. what is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
