gives us:
-----------------------------------------------------
Combine like terms:
We aren't allowed to have a coefficient bigger than 1.
I'm going to replace 
with 1 and 
with 
:
I want a number:
Combine like terms:
:
Combine like terms:
We can rewrite the first term by law of exponents:
So the binary form is:

Keep in mind 1+1=10 and that 1+1+1=11:
Setup:
1 0 1 1
+ 1 1 1
------------------------------
(1) (1) (1)
1 0 1 1
+ 1 1 1
------------------------------
1 0 0 1 0
I had to do some carry over with my 1+1=10 and 1+1+1=11.
Given:
To find:
The length of QR.
Solution:
We have,
Then, 
(CPCTC)
Divide both sides by 4.
Similarity,
(CPCTC)
Divide both sides by 2.
Now,
Therefore, the correct option is d.
- Let x be the percentage of p.
- Therefore,

Doubt clarification - use comment section.
So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.
