Answer

-13/3

Work Step by Step

1. Substitute values of p, q, and r into numerator of equation. -(-4 + 2)^{2} - 3(-10) First solve parentheses, then exponents, then multiply, then subtract. -(-2)^{2} - 3(-10) = -4 - 3(-10) = - 4 + 30 = 26 2. Substitute values of p, q, and r into denominator of equation and solve. 2 - 8 = -6 3. Divide numerator by denominator. 26/(-6) = -13/3
