Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64

Answer:
Step-by-step explanation:
As written, they all are linear functions.
If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.
The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.
___
A linear function is a sum of terms that are either constant or containing a single variable to the first power.
