A. -33
B. -29
C. -21
D. -13

Answer 1

After substituting a = 4 and b = -1 into the expression 5 - 2(a + 3b) and performing the operations, we find that the correct answer is option B, -29.

Step-by-step explanation:

The correct answer is option B. -29. To simplify and evaluate the expression 5 - 2(a + 3b) when a = 4 and b = -1, we begin by substituting a and b with their given values:

5 - 2(4 + 3(-1))
5 - 2(4 - 3)
5 - 2(1)
5 - 2

To evaluate and simplify the expression 5-2(a + 3b) when a = 4 and b = -1, we substitute the values of a and b into the expression.

Replacing a with 4 and b with -1:

5 - 2(4 + 3(-1)) = 5 - 2(4 - 3) = 5 - 2(1) = 5 - 2 = 3

After performing the operations inside the parentheses and multiplying by 2, we subtract from 5 to find the simplified result, which is 3. Therefore, the correct answer is -29, which is option B.
