Expand: In 2a^3/b^4

In 2 + 3 In a - 4 In b
In 2 - 3 In a - 4 In b
In 2 - 3 In a + 4 In b

in 2-3 in a 4+4 IN B

Step-by-step explanation:

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.
