Solve the proportionx+1 14 = x-1 20 a. -3/17 b.10/7 c.7/10 or d. -17/3

x = -17/3

Step-by-step explanation:

x+1 / x-1 = 14/20

20(x + 1) = 14(x - 1)

20x + 20 = 14x - 14

20x - 14x = -14 - 20

6x = -34

x = -34/6

x = -17/3

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
