4kj of energy are supplied to a machine used for lifting a mass. The force required is 800N. If the machine has an efficiency of 50%. To what height will it lift the mass?​

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )
