Question

Evaluate this expression if a = 2, b = -1 and c = 1.

Answer 1

Substitute the values into the equation

2(2)+4(-1)-5(1)
4-4-5
-5

Answer 2

Answer:

The answer is D. -5.

Step-by-step explanation:

Substitute the variables: 2(2) + 4(-1) - 5(1)

Multiply 2 by 2, and you get 4. Add 4 by the product of 4 and -1, which is -4, and you get 0. Subtract 0 by the product of 5 and 1, which is 5, and you get -5.
