They are exactly the same thing
Here, Both variable is in x form, so just add their coefficients,
5x + 6x = 11x
In short, Your Answer would be 11x
Hope this helps!
We can use Pythagorean theorem for right angle triangle to solve this problem.
The diagonal line would be hypothenuze. Horizontal and vertical distance would be other two sides of a triangle.
We will use the following formulas:

Where opposite side is vertical distance and adjacent side is horizontal distance.
Solving for these two sides we have:

We insert numbers and we get solution:
Answer:
1. 
2. 
Step-by-step explanation:
1. Solution for 1st part.
Given:
Ben shared his post with 2 friends
Each of those friends shares with 3 more every day.
the number of shares triples every day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

2. Solution for part 2.
Given:
Carter shared his post with 10 friends.
each share with only 2 people each day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

Answer:
1/8 of a minute
Step-by-step explanation:
Let the total time be t.
=> 1/2 x t = 1/16
=> t = 2/16
=> t = 1/8 of a minute
