To evaluate the expression when c = -5 and d = 2, substitute -5 for c and 2 for d in the given expression.

4(3d + 2c) + 12
= 4(3(2) + 2(-5)) + 12
= 4(6 - 10) + 12
= 4(-4) + 12
= -16 + 12
= -4

Therefore, the answer is 1. -4

To evaluate the expression when x = -1, y = -8, and z = 1/4, substitute -1 for x, -8 for y, and 1/4 for z in the given expression.

xyz
= (-1)(-8)(1/4)
= 8/4
= 2

Therefore, the answer is 1. 2.

To evaluate the expression when w = 3, x = -2, y = 6, and z = 0.5, substitute 3 for w, -2 for x, 6 for y, and 0.5 for z in the given expression.

yz/w + 2x
= (6)(0.5)/3 + 2(-2)
= 3/3 + (-4)
= 1 + (-4)
= -3

Therefore, the answer is 2. -3.
