To find the length of the expression [tex]\(17x - 18\)[/tex], we need to consider each character in the expression separately and then count the total number of characters.
Here is the expression: [tex]\(17x - 18\)[/tex].
Let's break it down by each character and count them:
1. The digit '1'
2. The digit '7'
3. The variable 'x'
4. A space ' '
5. The minus sign '-'
6. Another space ' '
7. The digit '1'
8. The digit '8'
Now, let's count all the characters:
1, 2, 3, 4, 5, 6, 7, 8
There are 8 characters in total in the expression [tex]\(17x - 18\)[/tex].
Therefore, the length of the expression [tex]\(17x - 18\)[/tex] is [tex]\(8\)[/tex].
