How many real solutions does t2+70=87 has

Two real solutions:   t = ±√17

Step-by-step explanation:

t^2 (not t2) + 70 = 87 is a quadratic equation that can be rewritten as t^2 = 17.  This equation has two real solutions:  t = ±√17

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
