The volume of the triangular pyramid is 1980 cubic yards.
To find the volume of a triangular pyramid, we need to multiply the area of the base by the height and divide the result by 3. In this case, the base has an area of 330 square yards and the height is 18 yards.
So, the volume of the pyramid is given by:
Volume = (Base Area * Height) / 3
Plugging in the values, we get:
Volume = (330 * 18) / 3 = 1980 cubic yards.

You want to isolate one of the variables (x or y) so you can plug it into the other equation. The easiest one is isolating the 2nd equation.
3x² - 16x + 13 - y = 0 Add y on both sides
3x² - 16x + 13 = y
You can use this and plug it into the first equation
y - 12x + 15 = 3x²
(3x² - 16x + 13) - 12x + 15 = 3x²
3x² - 16x + 13 - 12x + 15 = 3x² Combine like terms
3x² - 28x + 28 = 3x² Subtract 3x² on both sides
-28x + 28 = 0 Add 28x on both sides
28 = 28x Divide 28 on both sides
1 = x
Now that you know x, you can plug it into either of the equation to find y
3(1)² - 16(1) + 13 - y = 0
3 - 16 + 13 - y = 0
-y = 0 Divide -1 on both sides
y = 0
x = 1, y = 0
