To find the area of parallelogram rstu, juan starts by drawing a rectangle around it. each vertex of parallelogram rstu is on a side of the rectangle he draws. on a coordinate plane, parallelogram r s t u has points (negative 4, negative 3,) (negative 5, 1), (4, 3), and (5, negative 1). which expression can be subtracted from the area of the rectangle to find the area of parallelogram rstu? 2 (18 + 4) one-half (18 + 4) (18 + 4) (18 - 4)

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
