The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.
<h3>How to find the numeric value of an expression?</h3>
The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.
For this problem, the expression is given by:
d² + 3a + 6 + a
We want to find the numeric value when a = 2 and d = 5, hence:
5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

Answer:
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
Calvin one hour work = 
Alvin one hour work = 
To find out how much they can do together per hour,
We have to add and
= 
= 
--------------(1)
They can do of the job per hour.
If "t" is the time taken to finish the job together, then one hour work
------------------------(2)
Now we have to find the value of "t" by setting the expression (1) and (2) equal.
It can solve by flipping the equation;
t = 3.6 hours
It will take 3.6 hours to wax a car if they work together.
Yes this is proportional!
