Simplify the expression (2x − 9)(x + 6).
a.
2x^2 − 54
b.
2x^2 − 3x − 54
c.
2x^2 + 3x − 54
d.
2x^2 + 21x − 54

The answer is C.

Hope this helps.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
