Answer:
A
Step-by-step explanation:

x+2=0
x+2-2=0-2
x=-2.....(x+2) was squared...exponent of 2...multiplicity of 2
x-4=0
x-4+4=0+4
x=4....(x-4) has no visible exponent which means it is essentially to the power of 1...multiplicity of 1
x+1=0
x+1-1=0-1
x=-1....(x+1) was cubed...exponent was 3...multiplicity of 3
Sqrt(9)÷25= 0.12 I hope this helps!
4x4x4=64 so its volume is 64
Just finished doing the math and the correct answer should be B: 5.3 Hope this helps:)
