The solution's something you can really easily pick up, I promise.
The solution is simply the point where the two lines connect.
In this case, it's (2,5). (x,y)
Hope this helped!
(Khan Academy is a great resource.)
The sum of the angles of a triangle is equal to 180°.
x+65+79 = 180
x = 180 - 65 - 79
x = 36°
10ax + 5bx - 8ay - 4by = 5x(2a + b) - 4y(2a + b) = (5x - 4y)(2a + b)
option d is the correct answer.
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
