Answer:
See below
Step-by-step explanation:
Polynomials are sums of terms in the form of k⋅xⁿ, where k is any number and n is a positive integer. For example, 3x²+2x-5 is a polynomial.
Answer is : 8v^3+ 14v^2+11v+3
For cubic feet
Solution
Formula : volume base area x height
So base area = 4v^2 +5v+3
Height = 2v+1
So multiply
Volume =(4v^2+5v+3) x(2v+ 1)
The rest is below
The answer would be (3y-2)(3y-4)
9y^2-18y+8
=(3y-2)(3y-4)
.57 because 57/100 is like 57% and pretend that the percent is like a magnet and pulls the decimal two spaces to the right
