Let's solve the problem step by step.
We are given that [tex]\( x = 5 \)[/tex].
1. We need to find the value of [tex]\( 6x \)[/tex].
[tex]\( 6x \)[/tex] means we need to multiply 6 with the value of [tex]\( x \)[/tex].
2. Substitute [tex]\( x = 5 \)[/tex] into the expression [tex]\( 6x \)[/tex]:
[tex]\[
6 \times 5
\][/tex]
3. Perform the multiplication:
[tex]\[
6 \times 5 = 30
\][/tex]
Hence, [tex]\( 6x = 30 \)[/tex].
So, the correct answer is [tex]\(\boxed{30}\)[/tex].
