(Kind of a late question) but what is the most difficult algebra equation that you somehow got right?, this is for students and teachers, (for anyone really)

9.5x-2.5y=3+2x+.5y

Step-by-step explanation:

11.5x-3=3y

11.5/3 x-1=3

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
