Which function is nonlinear ?y=4x^3 , y=4x+3 , y=-4/3x

y=4x³ is not linear

Step-by-step explanation:

All of the equations produce lines, one of the characteristics of a linear function, except for y=4x³ where the graph is a curve. Refer to the graph attached to see this.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
