X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
Answer:
and two parts r equal btw but look below
Step-by-step explanation:
A circle is a geometric figure that needs only two parts to identify it and classify it: its center (or middle) and its radius (the distance from the center to any point on the circle). After you’ve chosen a point to be the center of a circle and know how far that point is from all the points that lie on the circle, you can draw a fairly decent picture.
Formula is l x w x h
50x28x33=46200 cm^3
last choice 46,200 cm^3
Answer:
the most closest answer is D because the formula is 3.14 x radius² x height
