Use the long division method to find the result when 6x3 + 11x2 + 21x + 6 is
divided by 3x + 1.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
