C. 9 square roots of 2

To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:

Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by \sqrt{2} will be 18. Knowing this, we can write out an equation:

u*\sqrt{2} = 18

u = \frac{18}{\sqrt{2} }

<u>Multiply both sides by </u>\sqrt{2}<u> in order to get rid of the root in the denominator:</u>

u = \frac{18*\sqrt{2}}{\sqrt{2} * \sqrt{2}}

u = \frac{18*\sqrt{2} }{2}

u = 9\sqrt{2}

If you'd like me to explain how I got to the answer any further, just ask!

Explain in words, how you to find a solution for the following equation. 7 + x = 18
zheka24 [161]

Answer:

x=11 (read below)

Step-by-step explanation:

7 + x = 18

<em>Subtract 7 from both sides</em>

x=11

It's quite simple because if you do something to one side of the equation, you need to do it to the other because otherwise the equation won't be equal. This is how you need to simplify most problems, by taking something from one side and taking from the other as well.
