Answer:
C) The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
sqrt(b² - 4ac) is not equal to
b - sqrt(4ac)
Because when you square b - sqrt(4ac), it's not b² - 4ac..
(b- sqrt(4ac))² = b² - 2bsqrt(4ac) + 4ac
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.

Step-by-step explanation:
The formula for a triangular pyramid is 1/3AH. A is the area of the base. H is the height of the pyramid. So to find the area of a right triangle, you would use the formula (a x b)/2. So (10 x18)/2 is 90 inches^2. Now you can fill in the first formula. 1/3(90 x 14), which equals 420 inches^3. I hope you find this helpful (if correct.)
