What is the binomial expansion of (m+2)^4

(m+2)⁴ = ((m+2)²)²

= (m² + 4+ 2m)²

= m⁴ + 8 + 4m² + 8m² + 16m + 4m³ ( (a+b+c)² = a²+b²+c²+2ab+2bc+2ac)

= m⁴ + 8 + 12m² + 16m + 4m³

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
