Trey is estimating the length of a room in his house. The actual length of the room is 17 m. Trey's estimate is 15 m. Find the absolute error and the percent error of Trey's estimate. If necessary, round your answers to the nearest tenth.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

it should be a and d. lmk if i'm wrong xd

78.59 is the mean

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
