they ask for the greatest number of minutes, so we round down (take the floor of the value).
the answer is 105 minutes.

Step-by-step explanation: IT'S NOT C OR D
Determine if the relation is a function.
The relation is not a function.
Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
the measures of the angles are:

How to find the measures of the angles?</h3>
Two angles are a linear pair if their measures add up to 180°.
Then we will have that:
∠EFG + ∠GFH = 180
Here we know that:
m∠EFG=3n+23
m∠GFH=2n+32
Replacing that we get:
3n + 23 + 2n + 32 = 180
5n + 55 = 180
5n = 180 - 55 = 125
n = 125/5 = 25
Then the measures of the angles are:
m∠EFG=3n+23 = 3*25 +23 = 98°
m∠GFH=2n+32 = 2*25 + 32 = 82°
