Answer: 1 and 21/100
Step-by-step explanation: Using the place value chart, we can see that 1.21 means 1 unit, 2 tenths, and 1 hundredth.
Think of 2 tenths and 1 hundredth as 21 hundredths.
So we have 1 and 21/100 which can
be written as the mixed number 
.
I have attached the place value chart below.
The equivalent expression is 2(4x+3)
- False. All whole numbers are integers.
- False. For example, 1/2 is a rational number but not a whole number.
- False. For example, -3 is an integer but not a whole number.
- True. All integers are included in rational numbers.

Doubt clarification - use comment section.
I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².
Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.
Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.
Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.
Add each length up and you get a perimeter of roughly 11.4
