Which of the expressions below can be factored using the difference of squares method?

zlopas [31]

Answer:

The second choice is correct. It can be factored as:

$9x^2-16y^2=(3x-4y)(3x+4y)$

Step-by-step explanation:

The Difference of Squares Method for Factoring

The expression:

$a^2-b^2=(a-b)(a+b)$

Is a widely used method to factor binomials that are expressed as the subtraction of two perfect squares.

The condition for a binomial to be factored by using this method is that both terms must have an exact square root and they must be subtracted.

The last two choices are not valid because they are not a subtraction but an addition.

The first choice is not valid because none of the terms is a perfect square.

The second choice is correct. It can be factored as:

$9x^2-16y^2=(3x-4y)(3x+4y)$

suppose that an 1994 finline produce 18.036 million lb of weed. The total World production that your total to 137 million lb of

Degger [83]

One may note the country's name is not finline or Finley, is Finland.

so, in short, if we take 137 to be the 100%, how much is 18.036 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
137&100\\
18.036&x
\end{array}\implies \cfrac{137}{18.036}=\cfrac{100}{x}\implies x=\cfrac{18.036\cdot 100}{137}$
