Find the following when a = -2, b = 3, c = -1/3
a^3 - 6c

That would be -34.

-2 times -2 times -2 minus 6 times -1/3

                                                 6/1 times -1/3 (cross multiply)

-16 minus 18= -34

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
