Answer:
2x+8
Step-by-step explanation:
I actually did the math
Turn hours into minutes
1hr = 60mins
Add the 60mins with 30mins since it’s 1hr and 30 mins. Which will equal 90mins
9miles/ 90minutes
You can simplify
1 mile/ 10 mins
So for 1 mile it takes 10 mins
And the problem is asking how much will it take for her to run 12 miles
Meaning it will take 120 minutes for her to run 12 miles.
The coefficients in the expression are -1 and 9
<h3>How to determine the coefficients?</h3>
The expression is given as:
-x^2 + 9x
In an expression ax, the coefficient is a.
Using the above as a guide, we have:
-x^2 + 9x
The coefficients in the above expression are -1 and 9
