Please help with this math

The multiplication property of zero states that the product of any number and 0 is 0. what must be true about either a or b to make ab=0

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

Solve the equation w^3 = 1,000 i honestly dont know how to punch this into a calculator pls
