Which is the completely factored form of 5w2 – 20?
5(W2 – 4)
5(W-2)(W - 2)
5(w - 2)(W + 2)
5(w + 2)(W + 2)

5(w - 2)(w + 2)

Step-by-step explanation:

5w² - 20

5(w² - 4)

5(w - 2)(w + 2)

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.

u also answered this so i think u would know but i am here to

put in or use mine
