Without multiplying, determine the sign of the product (356,864)(−194,758).

the sign of the product is positive because a positive multiplied by a negative is a positive.
the sign of the product is negative because a positive multiplied by a negative is a negative.
the sign of the product is negative because the second number is negative.
the sign of the product is positive because the first number is positive.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

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
