Answer: x= -4
Have to slove what’s inside the parentheses first so you distribute x & 4 from 6 which gives you 6x + 24 then you subtract 6x & -8x gives you -2x drop down the 24 & begin to do the math
So the equation for the volume of the pyramid is
. Using the info on the pyramid, we can form the equation 
Firstly, multiply everything on the numerator to get 
Next, just divide by 3, and your answer will be 
In short, the volume is 3408 un^3, or the first option.
X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.
2 x 1.5 = 3 inches
Hope this helps
