In the diagram, BC⎯⎯⎯⎯⎯∥DE⎯⎯⎯⎯⎯ .

RUDIKE [14]

The length of AE is $18in$

Explanation:

From the figure, we can see that the two triangles ΔAED and ΔACB are similar. Thus, the legs of the triangle are proportional to each other.

Thus, we have,

$\frac{EC}{DB} =\frac{AE}{AD}$

Substituting the values of the sides from the image, we get,

$\frac{3}{1} =\frac{AE}{6}$

Multiplying both sides of the equation by 6, we get,

$6(3)=AE$

Multiplying, we have,

$18=AE$

Thus, the length of AE is $18in$

Expand and simplify

likoan [24]

Answer:

5 $\sqrt{2}$ + $\sqrt{10}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

$\sqrt{5}$ ( $\sqrt{10}$ + $\sqrt{2}$ ) ← distribute

= $\sqrt{50}$ + $\sqrt{10}$

= $\sqrt{25(2)}$ + $\sqrt{10}$

= $\sqrt{25}$ × $\sqrt{2}$ + $\sqrt{10}$

= 5 $\sqrt{2}$ + $\sqrt{10}$
