2+3(2)^2/12
2+3(4)/12
2+12/12
2+1
Answer: 3
It’s y-axis for the first answer and the other one it’s
81a²-25 would be the answer I'm pretty sure. Hopefully I helped.
After solving for w using inverse operations, w would have to equal 5.74 to make this equation true.

Actually Welcome to the Concept of the Inequalities.
so we get as,
(w+6)/2 < 5
so we get as,
w+6 < 10
=> w < 10-6
=> w < 4
so the answer is,
w < 4
