3.14 is the decimal for pi
-3a^2 - b^3 + 3c^2 - 2b^3......when a = 2, b = -1, and c = 3
-3(2^2) - (-1^3) + 3(3^2) - 2(-1^3) =
-3(4) -(-1) + 3(9) -2(-1) =
-12 + 1 + 27 + 2 =
-12 + 30 =
18 <==
Answer:
6 minutes
Step-by-step explanation:
Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.

1/10 + 1/15 = [3(1) + 2(1)]/30
= 5/30 = 1/6
Their combined rate is 1/6 which means they check one set in 6 minutes
