To evaluate the expression [tex]\(x^2 + 14\)[/tex] for [tex]\(x = -5\)[/tex], follow these steps:

1. Substitute [tex]\(x\)[/tex] with [tex]\(-5\)[/tex] in the expression [tex]\(x^2 + 14\)[/tex].
2. Calculate [tex]\((-5)^2\)[/tex].

[tex]\[ (-5)^2 = (-5) \times (-5) = 25 \][/tex]

3. Add 14 to the result obtained in step 2.

[tex]\[ 25 + 14 = 39 \][/tex]

Thus, the value of the expression [tex]\(x^2 + 14\)[/tex] for [tex]\(x = -5\)[/tex] is 39.

Hence, the correct answer is:
D) 39
