General formula for area of triangle is
.
Where:
is height of triangle perpendicular to base side of triangle.
is the length of base side of triangle.
Multiplying
and
results in rectangle, dividing that by 2 gives you area of a triangle.
Hope this helps.

Picture graphs usually show amounts using...pictures! So if you looked
at the symbols, you can likely guess the amounts. It might show how many
students preferred hamburgers by using a hamburger to represent every 5
students. Just by quickly glancing at a picture graph, you can usually
tell which result is the greatest.
If B is the midpoint of AC, then AB=BC. It is also BC=AC-AB
AB = x + 6
AC = 5x - 6
BC = (5x - 6) - (x + 6)
We can kinda use distributive property, like this:
BC = 5x - 6 -x - 6
Combine like terms:
BC = 4x - 12
To verify, we can add AB and BC to see if their sum is equal to AC.
(x + 6) + (4x - 12) = 5x - 6
If we are correct, this equation will be true.
x + 6 + 4x - 12 = 5x - 6
Combine like terms:
6 + 5x - 12 = 5x - 6
5x - 6 = 5x - 6
It's correct!
BC = 4x - 12. Final Answer.
