Start with the slope formula and simplify.
Take a look below.
The original can be rewritten as 
. Because i^2 is equal to -1, we can replace the -1 in each radicand with i^2, like this: 
. Now, i-squared is a perfect square that can be pulled out of each radicand as a single i. 
. 24 has a perfect square hidden in it. 4 * 6 = 24 and 4 is a perfect square. So let's break this up, step by step. 
and then 
. We will now multiply the i and the 2i, and multiply the square root of 6 times the square root of 6: 
. 36 itself is a perfect square because 6 * 6 = 36. So we will do that simplification now. 
. Multiplying the 2 and the 6 gives us 
. But here we are back to the fact that i-squared is equal to -1, so 2(-1)(6) = -12. See how that works?
Answer: The required expression is 3x+4.
Step-by-step explanation:
Since we have given that
Let the number of wristbands that Shelly has be 'x'
Let the number of wristbands that Kaitaia has be
Let the number of wristbands that Rea has be three more than twice the number that shelly has be
According to question, the expression that shows the number of wristbands more Katia has than Rea is given by
Hence, the required expression is 3x+4.
