Answer:a 2 − b 2 = ( a + b ) ( a − b ) where a = 6 a and b = 7 b . ( 6 a + 7 b ) ( 6 a − 7 b
Step-by-step explanation:
Triangle: no parallel sides
square: 2 pairs of parallels (2 opposite sides are parallels)
trapezoid must have 1 pair of parallels
pentagon: if regular then no parallel, if not regular there can be 1 or 2 pairs of parallels
I believe the Answer is : 12/13
M = 135/19 and n = -5/19
You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.
