A triangle has vertices on a coordinate grid at L(9,7), M(9,-8), and N(1,7). What is the length, in units, of LM ?

Multiply. −2x(6 x 4 −7 x 2 +x−5) express the answer in standard form. enter your answer in the box.

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.
