Answer:
89
Step-by-step explanation:
51.62=52
36.557=37
----------------
52+37=89
6m+23
You have to use distributive property, so 15x2=30 and 2x3m= 6m. You then subtract 30 from 7 and get 23.
Just round 25.99 to 26 and divide it by two. This gives you 13, which is less than 14.. You would be able to buy the video game.
The discriminant of the equation
