If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s. t) (-7)

The base of a triangle exceeds the height by 7 centimeters. if the area is 400 square centimeters, find the length of the base and the height of the triangle.

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4

Solve the compound inequality. graph your solution. 2x – 2 < –12 or 2x + 3 > 7 x < –5 or x > 5 x < –5 or x > 2 x < –12 or x > 2 x < –7 or x > 5
