What is the approximate solution of this system of equations?
y=2x
y=3x
a) (0.5,1.4)
b) (-0.5,1.4)
c) (3.3,9.9)
d) (3.3,-9.9)

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
