Answer:

v = √(z(w+z))

Step-by-step explanation:

Right triangles in this configuration are all similar. That means the side ratios are proportional, so ...

long side/hypotenuse = z/v = v/(w+z)

Multiplying this equation by the product of the denominators, we have ...

z(w+z) = v²

Taking the square root gives ...

v = √(z(w+z)) . . . . . . matches the last selection

What is 2 times 5 to the 3rd power divided by (9-4) raised to the power of 4

Maslowich

Heyo Kiddo. How are you doing today?

Let's figure this out.

So in number form, the equation will be looking a little like this:

$2(5) ^{3} / (9-4)^4$

To solve.

$2(5) ^{3} / (9-4)^4 \ \textless \ Parenthesis first\ \textgreater \ 

2(5)^{3} / 5^4 \ \textless \ Exponents\ \textgreater \ 

2(125) / 625 (Multiply)

250 / 625 (Divide)

0.4 (Answer)$

So I hope this answers your question and that you have a great day. :)
