Answer:

5c+50

Step-by-step explanation:

5c comes from the 5 videos that cost <em>c</em><em> </em>dollars. 50 is when you add the $30 for the DVD and $20 for the CD together. You add those up to get the answer, but you'll have to solve for <em>c</em><em> </em>first, then you can solve it.

We need to find the hypotenuse of the triangle. We can find that by using the Pythagorean theorem: a² + b² = c²

Solve with the given values of the triangle:

2² + 4² = c²

4 + 16 = c²

20 = c²

√20 = √c²

4.47 ≈ c

Find the area of the square using: A = bh

4.47 * 4.47 = 19.9809

Therefore, the area of the square is approximately 19.9809units²

Best of Luck!

Simplify<br>-6√20+2√45+7√5 <br><br>show Woking out to prove ans please​
Dmitry_Shevchenko [17]

Answer:

\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{20} = \sqrt{4(5)} = \sqrt{4} × \sqrt{5} = 2\sqrt{5}

\sqrt{45} = \sqrt{9(5)} = \sqrt{9} × \sqrt{5} = 3\sqrt{5}

Thus

- 6(2\sqrt{5}) + 2(3\sqrt{5}) + 7\sqrt{5}

= - 12\sqrt{5} + 6\sqrt{5} + 7\sqrt{5}

= \sqrt{5}
