That depends. What are you trying to find? The formula for the perimeter? The formula for the area?
Because 5x4 is 20 but 5x1/4 is 1,25.
5 x 1 = 5... / 4 = 1,25
Or ... -> 1/4 = 0,25 * 5 = 1,25

6 adults were in the group and 4 children
X-45\x<-4(multiply both sides by X to remove the denominator )
X-45<-4x (collect the like terms)
-45<-4x+x
-45<-3x(divide both sides by -3
-45\-3<-3\-3x
15>x
G(x) = f(x) +5
= 4^x -6 +5
= 4^x -1
The 3rd selection is appropriate.
