Look up the formula to find the area of a trapezoid. Then do the math HINT: The formula is
A= a+b/2 h
8(2x-14)+13=4x-27
Use distribute property for the first one
16x-112+13=4x-27
16x-99=4x-27
12x=72
x=6. As a result, the value x is 6. Hope it help!
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:

so the slope is

the answer is -2
good luck
