rational expressions shown:
1 1
X-2 X + 1
x+1
x-2
(x - 2)(x+1) (x - 2)(x + 1)
-1
(x-2)(x+1)
DONE

3x^3-x^2+6x-9

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

the answer will be the last one
