Which equation is true when the value of x is -12?
A 20 - 2x = 4
B 1/4x+3 = 6
C 0.5x - 3 = 3
D 22 - 1/4x = 25

yes. we do proportions in probabilities.

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
