Answer:

13

Step-by-step explanation:

It is a quadratic equation meaning it has 2 factors and since one of it has root -5, the first factor is (n + 5),

So, we have (n + 5)(n + a) = n^2 + an + 5n + 5a

Thus, by comparison,

n^2 + (5 + a)n + 5a = n^2 - 8n - 65 = 0

5 + a = -8

5a = -65

a = -13

Thus, the other factor is (n -13) and root is 13

Answer:

the desired equation is y = -5x + 2

Step-by-step explanation:

The general slope-intercept form is y = mx + b.  Here we know that m = -5 and b = 2, so the desired equation is y = -5x + 2.

Answer:

u = \sqrt{6}.

Step-by-step explanation:

This is a 45-45-90 triangle.

That means that there are two side lengths with lengths of x, and a hypotenuse with a length of xsqrt(2). We can then set up a proportion.

\frac{1}{\sqrt{3} } =\frac{\sqrt{2} }{u}

1 * u = \sqrt{3} * \sqrt{2}

u = \sqrt{6}.

Hope this helps!
