Devin tried to find the derivative of

11
−3x−11minus, 3, x, minus, 11 using basic differentiation rules. here is his work:

=−3⋅1
=−3


at which step did devin make a mistake, if at all?

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

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

the answers might not be correct use at own risk

the median is   36 orr sum like dat
