Answer :

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].
