a) 3(-2) + 4(3) = -6 + 12 = 6
b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8
c) 4(-2) -(3) = -8 -3 = -11
d) -(-2) -2(3) = 4 -6 = -2
e) (1/2)(-2) +(3) = -1 +3 = 2
f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3
Cos -2x or -cos2x, it's the difference.
U,U you need to divide how many cards in total the subtract and mulitply them
It would be 23.5 idk if your aloud to do that
or 141/6
4.5x67=301.7
6/5x78=63.6
20-100+3000=2920
