Sagot :

To determine the value of the expression [tex]\(w^2 + 3w - 11\)[/tex] when [tex]\(w = -5\)[/tex], follow these steps:

1. Substitute [tex]\(w\)[/tex] with [tex]\(-5\)[/tex] into the expression:
[tex]\[ w^2 + 3w - 11 \quad \text{becomes} \quad (-5)^2 + 3(-5) - 11 \][/tex]

2. Calculate the square term [tex]\((-5)^2\)[/tex]:
[tex]\[ (-5)^2 = 25 \][/tex]

3. Calculate the product [tex]\(3 \times (-5)\)[/tex]:
[tex]\[ 3 \times (-5) = -15 \][/tex]

4. Combine these results with [tex]\(-11\)[/tex]:
[tex]\[ 25 + (-15) - 11 \][/tex]

5. Perform the addition and subtraction step-by-step:
[tex]\[ 25 - 15 - 11 = 10 - 11 = -1 \][/tex]

So, the value of the expression [tex]\(w^2 + 3w - 11\)[/tex] when [tex]\(w = -5\)[/tex] is:
[tex]\[ \boxed{-1} \][/tex]

The correct answer is D. -1.
