Answer: the answer is 3.1 square meters.
1/2 (2) + 3 + 5.3 (3)
1 + 3 + 15.9
19.9
Greatest common factor in this case is 2s^2. The resulting polynomial would be 2s^2(s^2-2)
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.
For the function

We can use the formula for the axis of symetry, which is

With the values substituted, we get...

Therefore the axis of symmetry is
