Answer:
9w+2/3
Step-by-step explanation:
add like terms
Its a even number, and also its a whole number.
The original volume of the shape was 250. You come up with this by multiplying all sides together. So, 5x5x10=250.
We do the same for the new shape, which now has a 7 in place of the 5. So 7x7x10=490.
Lastly, we subtract the volume of the new shape from the volume of the old shape to see the difference. So, 490-250=240.
So the answer to this is 240.
adding a negative number is the same as subtracting a positive number. This question is the same as 10.5-8.3
