Answer:

108

Step-by-step explanation:

We can rewrite f(x+2) to make it easier to evaluate:

f(x+2) = (6x +5)x -8

Since we want f(6), we want x+2 = 6, or x=4.

f(6) = (6·4 +5)·4 -8 = 29·4 -8

f(6) = 108

Write in simple radical form:

WARRIOR [948]

Answer:

The answer to your question is $\frac{2}{3}$

Step-by-step explanation:

Here, there is a difference of squares, so just solve it and simplify

$( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )$

Multiply the binomials

= 1 - $\frac{1}{3}$

Simplify

= $\frac{3 - 1}{3}$

= $\frac{2}{3}$
