Because when you build things with real wood and tools, negative length has no physical meaning. There are still two square roots, but we ignore the one that's not useful.

How do you solve for the Rations of Special Triangles? This is confusing
Bogdan [553]

Answer:

The answer to your question is  x = \frac{3\sqrt{2}}{2}

Step-by-step explanation:

Data

right triangle

x = ?

hypotenuse = 3

To solve this problem use trigonometric functions. The trigonometric function that relates the opposite side and the hypotenuse is sine.

            sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

            x = hypotenuse  sin 45

-Substitution

 sin 45 = \frac{\sqrt{2}}{2}

            x = 3\frac{\sqrt{2}}{2}

-Solution

            x = \frac{3\sqrt{2}}{2}  It is not possible to simplify any more.

-78 = -6 (p - 4)i don't understand it​
iris [78.8K]
Distribution is one of the most important terms of math you need to know.

Distributing, in this case, is when you take the -6 and multiply the terms in the parenthesis.

When you do that. You’ll get -78 = -6p+24.

*Remember: a negative times a negative is always positive. A positive times a negative is always negative. If you need more help with this tip, please feel free to reply if you need any better tips and tricks.

Now, you’re going to solve -78-24 (since you switch the sign when you bring one term to the opposite of the equation).

Then you’ll have -102 = -6p

Lastly, instead of multiplying, you divide -102 by -6.

Your final answer should be 17 = p (or flip it to make it p = 17).
