Find constants a and b such that {x + 7}/{x^2 - x - 2} = {a}{x - 2} + {b}{x + 1} for all x such that x is not equal to -1 and that x is not equal to 2. give your answer as the ordered pair (a, b) ! just the answer, .

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
