Bruh, you need a math tutor.

2x-5 is twice a number decreased by 5.
twice the value of 5 in 2851 = 100
What is the quotient of twice the number and three
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
Twice-differentiable simply means that the function can be differentiated twice. eg. If y = x^5 (^5 means to the power of 5). Then y' = 5x^4 (i.e. differentiating once) Then y'' = 20x^3 (differentiating twice)

2x+5
2x + 5 =
2n + (-5)
270
It is 80.
