Answer:

(x + 6y)(x - 3y)

Step-by-step explanation:

Given

x² + 3xy - 18y²

Consider the factors of the coefficient of the y² term (- 18) which sum to give the coefficient of the xy- term (+ 3)

The factors are + 6 and - 3 , since

6 × - 3 = - 18 and 6 - 3 = + 3 , then

x² + 3xy - 18y² = (x + 6y)(x - 3y)

Answer:

$\frac{12}{13}$

Step-by-step explanation:

We are asked to find the exact value of $\cos(\arcsin \frac{5}{13})$ .

Firstly, let's call $y = \arcsin \frac{5}{13}$ ⇒ $\sin y=\frac{5}{13}$ .

Since $\cos(\arcsin \frac{5}{13})=\cos y$

$\cos(\arcsin \frac{5}{13}) = \sqrt{1-\sin^2y}=\sqrt{1-(\frac{5}{13})^2}=\sqrt{1-\frac{25}{169}}=\sqrt{\frac{144}{169}}=\frac{12}{13}$
