Simplify:4sqrt400/4sqrt5. Show your work.

Deffense [45]

$\frac{4 \sqrt{400} }{4 \sqrt{5} } = \frac{ \sqrt{400} }{ \sqrt{5} } = \\ \frac{20}{ \sqrt{5} } * \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{20 \sqrt{5} }{5} } = 4 \sqrt{5}$
Thank you.

The formula for the area of a triangle is A=12bh. Solve this equation for b.

aksik [14]

Step-by-step explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.
