Answer:

$\sqrt{10+4\sqrt{6 }$ = 4.44948

or = $\sqrt{6} + 2$

step by step...solving

10 + 4 $\sqrt{6}$

add/subtract $\sqrt{6}$ ² = 6

=10 + 4 $\sqrt{6}$ + $\sqrt{6}$ ² - 6

Refine

= $\sqrt{6}$ ² + 4 $\sqrt{6}$ + 4

rewrite ↑ as $\sqrt{6}$ ² + 2 $\sqrt{6}$ * 2 + 2²

apply Perfect Square Formula (a + b)² = a² + 2ab +²

a = $\sqrt{6}$ , b=2

= ( $\sqrt{6}$ + 2)²

= $\sqrt \sqrt({6}+ 2)$ 2square

(the 2 square would not fit like i wanted it to)

apply radical rule $\sqrt[n]{a^{n} } = a$ , assuming a ≥ 0

= $\sqrt{6} + 2$

posting others as picture (have an account with Symbolab to help me as well. Just taking too long to type in the step by step if you need it. all pictures have the decimal result.

I need to solve for x. I'm so confused with the whole 'Slide splitting theorem' thing

Triangles JFE and JLK are similar provided that line segments FE and LK are parallel. This means that corresponding parts of these triangles occur proportionally to one another. In particular,

$\dfrac{JF}{JL}=\dfrac{JE}{JK}=\dfrac{FE}{LK}$
