Answer:
Brad in total drove approximately 361 miles.
Step-by-step explanation:
Renting Cost per day of car = $26. 95
Cost per mile= $0.33
So, cost of renting car 3 days = 3 x $26. 95 = $80.85
Total money spent on the trip = $80.85
So, the actual spent money on distance = Total money spent - The renting charge
= $200 - $80.85 = $119.15
So, Distance travelled = 
= 
or, number of miles traveled = 361
So, Brad in total drove approximately 361 miles.

Answer:
A, C
Step-by-step explanation:
First of all, recognize that any basic arithmetic operation between a rational number and an irrational number will have an irrational result. That means, you can eliminate any answer choices that involve an irrational number.
Fractions and mixed numbers involving integers are <em>always rational</em>, so you only need to look at the radicals. You know 9 is 3×3, so is a perfect square, and √9 = 3 is rational. You know 5 is not a perfect square, so <em>√5 is irrational</em>.
Considering the above, any expression involving √5 will have an irrational result. That means you can eliminate choices B and D.
choices A and C will result in a rational number
_____
<em>Additional comment</em>
A = 6.8 +0.75 = 7.55 (rational)
C = 6.8 × 0.75 = 5.100 (rational)
The factored form of n2 + n is: n(n+1).
<h3>How to find the factored form?</h3>
Given data:
n²+n
Now let find the factored form of n²+n
n²+n
Rewrite in factored form
n(n+1)
Hence,
n²+n = n(n+1)
Therefore n(n+1) is the factored form.
