No, it is not an example of a nonlinear relationship because there is a steady rate of change.
A nonlinear equation does not produce a straight line and the exponent is to the second power or more. x square plus 3y =5 is an example of a nonlinear equation.
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
(a + x^2)(b + y^2)
(x+y)2
No.
Y=x^2
X = √63
One plus cosecant squared x is equal to cotangent squared x.
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
x=9 squared
If x is equal to 5, then x squared plus 25 is equal to 50.
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
