How do you find the area of a triangle if you only know it's three sides?

You would have to find the height.

To do this, you cut the triangle from the upper vertex to the base to create two new triangles.

Then you use the Law of Cosines. You could use the google calculator for this by searching “law of cosines calculator” and inputting the values, but in case of a test, the formula is a^2 = b^2 + c^2 - 2bc cosA

If you could provide an example of a triangle, I will gladly help you with the steps! Hope this helped!

Suppose there were m married couples, but that d of these 2m. people have died, Regard the d deaths as striking the 2m people at
iren2701 [21]

The function that represents surviving people are X = 2m - d

Given that there are m married couples and d of the 2m of these couples have died, the total people that remain is expressed as:

Total people remaining = Total married couple - those that died

Total married couple = 2m

Total people that died = d

Taking the difference to get the remaining people;

Total people remaining = 2m - d

Hence the function that represents surviving people are X = 2m - d

What's next in -3x+2+9x=4x-5-1
sweet [91]
Firstly, you need to combine like terms within that side of the equation.
Take -3x +9x and you’ll get 6x.

Next, combine like terms on the other side of the equation.
Take -5-1 and you’ll get -6

So far you should have:
6x+2=4x-6

Subtract 4x on each side!! Cancel 4x-4x! Solve 6x-4x!

Now you’ll get:
2x+2=-6

Subtract 2 on each side!!
Cancel out 2-2 and solve -6-2.

You should get:
2x=-8

Lastly, divide 2 on each side.
Cancel out 2/2 and solve 8/2.

Your final answer should be:
X = -4
