Given the area of the shaded trapezoid, find x.
Show all work.

A. 90 degrees b. 45 degrees c. 30 degrees d. 120 degrees

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
