Answer:

Polynomial is the general term, but some polynomials can be classified in a more specific way.

Step-by-step explanation:

This is exactly how Polynomials work: Polynomial is the general term, but some polynomials can be classified in a more specific way. A polynomial is any sum (or difference) of terms. A term is separated by a plus or minus sign (that's why the word sum is used). Some polynomials can be classified more specifically as monomials, binomials, or trinomials.

stepan [7]

Answer:

Step-by-step explanation:

Given that a solution containing 12% alcohol is to be mixed with a solution containing 4% alcohol to make 20 gallons of solution containing 9% alcohol.

Let x gallons of 12% alcohol be mixed with y gallons of 4% alcohol.

Total gallons $= x+y = 20$

Alcohol content in the total mixture $= 0.12x+0.04y =9% of x+y$

$0.12x+0.4y=0.09(20)\\12x+4y = 180$

b) Two equations are

$x+y = 20\\12x+4y = 180$

c) This is of the form Ax = B

where A = $\left[\begin{array}{ccc}1&1\\12&4\end{array}\right]$

Inverse is $\frac{1}{4-12} \left[\begin{array}{ccc}4&-1\\-12&12\end{array}\right]\\=\frac{-1}{8} \left[\begin{array}{ccc}4&-1\\-12&12\end{array}\right]\\$
