Please help. Im dying for the explanation. I will mark you brainalist.
AlekseyPX

Step-by-step explanation:

Given that the mean of the numbers is 12

mean =  \frac{sum \:  \: of \: observations}{total \: number \: of \: observations}

so here

let's that one as x and another one as 2x since it is given that one is twice the other

Therefore we get

mean =  \frac{13 + x + 4 + 16 + 6 + 2x}{6}

Given mean = 12

12 =  \frac{39 + 3x}{6}

72 = 39 + 3x

3x = 33

x = 11

Hence it's 11 and 22

1b) use letter "L" or "x"

1c) Formula: P=4L or P=4x

2) the formula for the perimeter of a square is P=4L or P=4x because to find the perimeter you have to add up all the sides, and for a square, all the sides are equal, so it is P=4L or P=4x.
