Answer:
30 ( I think so)
Step-by-step explanation:
Well, the total measurement 4 a triangle is 90. So 60 and 60 is 120 so it should be 30. If not I am sorry for being wrong.
1. set up the equation which makes these shapes equal, 1/2(2(x+1)) = 1x
2. solve, x+1=x, 1=0
3. since this is impossible, there is no solution and zero answers

You can use (a+b)2 = a2+2ab+b2.
(2x - 3)2 = (2x)2 + 2(2x)(-3) + (-3)2 = 4x2 - 12x + 9
Or you can use FOIL.
(2x - 3)2 = (2x - 3)(2x - 3) = (2x)2 + (2x)(-3) + (-3)(2x) + (-3)2 = 4x2 - 12x + 9
