what is the value of 36x-8^2 when x=3 and y=-6   

 

Is that 36x minus 8 squared? 

 

When x=3 then           (36 • 3) – (8 • 8) 

 

                                    108 – 64  =  44 

 

                                     and it doesn't matter what y equals 

.

There is no "y" involved...

 

36x - 8^2.

 

36 * 3 - 64

 

108 - 64

 

44
