Let's find the value of given expression for x = 5 ~
now, plug in the value of x as 5
so, the equivalent value is 60
This number should be 10.
The tens digit the the 1st number on a two-digit number. Because the highest number you can go without creating a hundredths place is a 9, and the question says the ones-place (the last digit), this has to make this number 0. If it were to be 1 or anything higher, it would have to create a hundredths place if the rule of the question were to be followed.
Example:
If ones-place were 1, then following rule: 1+9 = 10
Your number would end up being 101 instead of a tenths place number.
I hope that made some sense somewhere!

Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is <em>not satisfied</em>.

<em>Additional comment</em>
You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.
