Answer:

Step-by-step explanation:

volume V1=4/3 π(r1)³=4/3 π×7³

V2=4/3 π(r2)³=4/3 π×4³

V1-V2=4/3 π(7³-4³)=4/3π(343-64)

=4/3×π×279

=4π×93

=372π mm³

Answer:

2x for the first term

The whole thing is 2x+3

Step-by-step explanation:

Think of it like normal division

What will get the closest answer to 2x^2+x?

2x*x-1=2x^2-2x

Now the expression is 3x-3 so if you but 3 than it becomes 3x-3 which would be a remainder of 0

23 points to whoever can answer this question !!
yKpoI14uk [10]

I do believe that that point is -2.2 because of the fact that the difference between -1.6 and -2.4 is 0.8, and there are 4 marks in between them. So each mark's value is decreased by -0.2.

Jahyib has 421 dollars. He has 152 dollars more than kelsyann. How much money do Jahyib and Kelsyann have altogether?
zaharov [31]
Both of them together have 690 because you subtract 152 from 421 so...

421-152=269

Then add 269 to 421

421+269=690
