The equations that are correct are n = 10, CF = 59 and FE = 42
Properties of a parallelogram
From the attached diagram, we can see that the opposite side of the parallelogram are equal, hence;
DE = CF
6n - 1 = 5n + 9'
Find the value f n
6n - 5n = 9 + 1
n = 10
CF = 5n + 9
CF = 5(10) + 9
CF = 59
For the measure of FE
FE = 4n + 2
FE = 4(10) + 2
FE = 42
Hence the equations that are correct are n = 10, CF = 59 and FE = 42
