Last question on my assignment and I have no idea how to do it! I really need help.​

Answer 1

310

Explanation:

divide this figure into two rectangles, one with length of 3x-7 and width of x, the other one with length of 2x and 5x+2. plug x=5 into these, the first rectangle's area is 5*8=40, the second rectangle's area is 10*27=270. 40+270=310
