The area of the triangle below is 7.5 units
If you would like to simplify (3 * x + 5) + (2 * x - 9) - (4 * x + 3), you can do this using the following steps:
(3 * x + 5) + (2 * x - 9) - (4 * x + 3) = 3 * x + 2 * x - 4 * x + 5 - 9 - 3 = 1 * x - 7 = x - 7
The correct result would be x - 7.
Answer:
BFC makes this angle add up to 90 degree at BFD
Therefore it becomes complementary to angle CFD
subtract 14 from 22 to isolate the variable
