17.97 + 25.49 + 3x = 50.33
17.97 + 25.49 + 3x - 17.97 - 25.49 = 50.33 - 17.97 - 25.49
3x = 6.87
3x/3 = 6.87/3

Make all fractions with a 48 denominator:
21/48 + 28/48 + 42/48 + 88/48
=179/48 = 3 (35/48)
You get (2x+3)(4x^2-6x+9) when you factor 8x^3+27=0. You just divide by 3 to simplify it.
The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
