Select the correct answer.

What is the value of this expression when [tex]w = -5[/tex]?

[tex]\[ w^2 + 3w - 11 \][/tex]

A. -51
B. -36
C. -16
D. -1



Answer :

Sure! Let's solve the expression [tex]\( w^2 + 3w - 11 \)[/tex] when [tex]\( w = -5 \)[/tex] step-by-step:

1. Start with the expression:
[tex]\[ w^2 + 3w - 11 \][/tex]

2. Substitute [tex]\( w = -5 \)[/tex] into the expression:
[tex]\[ (-5)^2 + 3(-5) - 11 \][/tex]

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

4. Multiply 3 by [tex]\(-5\)[/tex]:
[tex]\[ 3(-5) = -15 \][/tex]

5. Substitute these values back into the expression:
[tex]\[ 25 - 15 - 11 \][/tex]

6. Perform the subtraction:
[tex]\[ 25 - 15 = 10 \][/tex]
[tex]\[ 10 - 11 = -1 \][/tex]

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

Therefore, the correct answer is:
D. -1
