Which binomial is a factor of 9x2 – 64? 3x – 8 9x – 32 3x 32 9x 8
aalyn [17]

The binomial factor of the equation \rm 9x^2 -64 is 3x-8.

<h3>What is a binomial factor?</h3>

The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.

Factoring binomials means breaking down a binomial expression into its simplest form.

Binomials are algebraic expressions with two terms.

The given binomial is;

\rm 9x^2 -64

The binomial is determined in the following steps given below.

\rm =9x^2 -64\\\\= (3)^2x^2-8^2\\\\= (3x)^2-8^2\\\\= (3x-8)(3x+8)

Hence, the binomial factor of the equation \rm 9x^2 -64 is 3x-8.

Increase 160km by 30%
ella [17]
There are two ways you could do this:

1. (if you have a calculator) This is called decimal multipliers, and basically all you do is multiply 160 by 1.3 because 1.3 is 1 (160) and 0.3 (30%) so you would get 208.

2. (without a calculator) This is the 'long way'. You do 160 ÷ 10 = 16 = 10%, and then 16 × 3 = 48 = 30%. After this you just add 48 on to 160 to get 208.

Hope this helps!

Which of the following would not be a possible function for f (x) and g(x) such that f of g of x is equal to 6 over the quantity
Aleonysh [2.5K]

Option C is correct. the functions that would not be a possible function for f (x) and g(x) are f(x) = \frac{4}{x^2+2} and g(x) = x

Given the composite function

f(g(x))=\frac{6}{x^2+3}

We are to look for two functions f(x) and g(x) that will not give the same function

Using trial and error,

If f(x) = \frac{4}{x^2+2} and g(x) = x

Determine the f(g(x)) for this function

f(g(x)) = f(x)

This is gotten by simply replacing x with x in f(x). This will return back the function f(x) making this the right choice.

f(g(x)) = \frac{4}{x^2+2}

Since,  \frac{4}{x^2+2} \neq \frac{6}{x^2+3}, hence the functions that would not be a possible function for f (x) and g(x) are f(x) = \frac{4}{x^2+2} and g(x) = x
