-15x-40=15
then add 40 to both sides to get the constants on 1 side and variables on the other
-15x=25
now you just divide by -15
x = -1.67 or x = -1/3
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
