 the dimensions of the reduced rectangle are

scale factor=3/18.6------> 1/6.2
then 
the other dimension of the reduced rectangle is 
31*(1/6.2)-----> 5 mm

perimeter of the reduced rectangle=2*[3+5]-----> 16 mm

Answer:

we need to find out if the following get x = 2 as a final product

-2(x-4) = 4

-2x + 8 = 4

-2x = -4

x = 2

so it is a solution

26/x = 13

26 = 13x

x = 26/13

x = 2

so it’s a solution

-3.8x = -7.4

x = 7.4/3.8 ≠ 2

you get ≈ 1.95

so it’s not a solution

4(x-1) - 3(x-2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -10

so it’s not a solution
