It should be B.
2x-x+3 = 8
x = 5
plug into second equation
y=5-3
y=2
(5,2)
Answer: 126 cubic centimeters
Step-by-step explanation:
volume = (pi)(r^2)(1/3)(h)
diameter = 8 so radius = 4
4 squared is 16
multiply height by 3/4
10(3/4) = 30/4 = 15/2
Multiply this value by 1/3
15/2 x 1/3 = 15/6 = 5/2
(pi)(25)(5/2)
16x5/2 = 80/2 = 40
(pi)(40)
note: you can substitute 3.14 with pi or use actual pi depending on whether or not you have access to a calculator. they will both round to 196.
126 cubic centimeters
Distribute :
3(2+7)=6(4)−3
6x+21=6(x+4)-3
The height should be C.) 400 mm. Hope this helps!! <3
