The answer is 18cm for the radius
I believe the answer is (x+3)x(x-1) hope this helps
I believe its d because you subtract (-3 -7 1 9) from both sides
There are 65 Liters in 6500 centiliters.
1 cl = 0.01 L, so 0.01 x 6500 = 65
Let x= 2.3181818...
then
10x=23.181818... and
1,000x=2,318.1818...
1,000x-10x=2,318.1818...-23.181818...
990x = 2,318 - 23
990x = 2295
x=2295/990
dividing by 5 both numerator and denominator:
x= 459/198
now, x= 198 + 198+ 63
so
