Factoring out (x-3), we get (7x^2+5) (x-3). That is your answer, I hope this helps :).
Answer:
28
Step-by-step explanation:
This is the concept of volumes of solid figures;
To calculate for the volume of material required we calculate for the volume of the pyramid;
volume of the pyramid is given by:
volume=(length*width*height)/3
but in our case the base of the pyramid is square, therefore:
length=width=2 ft
height=6 ft
hence;
volume=(2*2*6)/3
volume=8 ft^3
The answer is 8 ft^3
1st one is x=5
2nd one is x=-15
