Answer:
Option (1)
Step-by-step explanation:
Surface area of a cylindrical vessel is given by the expression,
Surface area =
=
Here, r = Radius of the vessel
h = Length of the vessel
By substituting the values of 'h' and surface area in the expression,
2πr(12 + h) = 540
Therefore, Option (1) will be the correct option.
Since the variable type of writing utensil assumes labels and not numbers, it is classified as qualitative.
<h3>What are qualitative and quantitative variables?</h3>
- Qualitative variables: Assumes labels or ranks.
- Quantitative variables: Assume numerical values.

Answer:
14x+3
Step-by-step explanation:
The given expression is as follows :
4x + 3(2x +1) + 4x
We need to find the equivalent expression for the above.
So,
4x + 6x +3 + 4x
Adding x terms,
14x+3
Hence, the correct equivalent expression is 14x+3.
2.5m 15 feet 12/5=2.5 and 75/5=15
