A =3(x+2)
A = 3x + 6

B= 2(x-7)
B = 2x - 14

C= -0.5(x+8)
C = - 0,5x - 4

D= 4(3x+1)
D = 12x + 4

E= -5(2x-6)
E = - 10x + 30

F= 2x (1+x)
F = 2x + 2x²
F = 2x² + 2x

I = 10(5 - 2 x) - 2(2 x -5)
I = 50 - 20x - 4x + 10
I = - 20x - 4x + 50 + 10
I = - 24x + 60

H = 2(x + 7) + 3(2 + x)
H = 2x + 14 + 6 + 3x
H = 2x + 3x + 14 + 6
H = 5x + 20
