-nr+70 <50

or,-nr+70-50 <50-50

or,20-nr <0

or,20-nr-20<-20

or,-nr<-20

or,nr/n<20/n

or,r <20/n

same as

4b-2d=25

or,4b=25+2d

or(4b-25)/2=d

Step-by-step explanation:

we must try to solve equation for answer

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
