9514 1404 393

  2

Step-by-step explanation:

A calculator can give you the answer quickly: 2.

Working this out in detail is a little more complicated. Eliminating roots in the denominator means multiplying numerator and denominator by the "conjugate" of the denominator.

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 answer will be b x² +x-1
