Let x be the number of weeks.
<u>Nick</u>
- weighs 160 pounds;
- is gaining about 3 pounds per week;
- gains 3x pounds in x weeks;
- weighs 160 + 3x pounds after x weeks.
<u>Adam</u>
- weighs 195 pounds;
- is losing about 2 pounds per week;
- loses 2x pounds in x weeks;
- weighs 195 - 2x pounds in x weeks.
The equation that can be used to find the number of weeks that it will take them to weigh the same amount is
Solve this equation:

Answer:
84
Step-by-step explanation:
This is in the form
ax^2 + bx +c
3x^2 +12x +5
a =3 b = 12 c =5
The discriminant is
b^2 - 4ac
12^2 - 4 * 3 *5
144 - 60
84
