We can first turn the text into a proper formula:
x plus 10 plus 6 x plus 2 x
x+10+6x+2x
The like terms are the numbers with
We can then put the like terms together to continue the calculation:
x+6x+2x+10
=9x + 10
Therefore, the answer is 9x + 10.
Hope it helps!

Answer:
Step-by-step explanation:
Hello, please consider the following.

So this is divisible by 3.
Now, to prove that this is divisible by 9 = 3*3 we need to prove that
is divisible by 3. We will prove it by induction.
Step 1 - for n = 1
4+17=21= 3*7 this is true
Step 2 - we assume this is true for k so
is divisible by 3
and we check what happens for k+1

is divisible by 3 and
is divisible by 3, by induction hypothesis
So, the sum is divisible by 3.
Step 3 - Conclusion
We just prove that
is divisible by 3 for all positive integers n.
