The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where
represents the smaller integer. Which equation can be factored and solved for the smaller integer?
1 x2 + x-72=0
x2+x+72 = 0
2 + 2x - 72 = 0
2 + 2x + 72=0

Intro

∆abc is reflected across the x-axis and translated 2 units up to give the image ∆a'b'c' with coordinates a'(1, 1), b'(2, -1), c'(2, 1). what are the coordinates of the preimage ∆abc? a. a(-1, 1), b(-2, 3), c(-2, 1) b. a(1, 1), b(2, 3), c(2, 1) c. a(1, -3), b(2, -1), c(2, -3) d. a(1, -3), b(2, -5), c(2, -3)
