If y=3x^3+x^2-5 and z=x^2-12 , which polynomial is equivalent to 2(y+Z)?

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

1/4 because there is 4 grades.
