Answer:
6
Step-by-step explanation:
the lowest common factor is 6
The perimeter of the rectangle is given by the formulae,

Where

is the length and

is the width of the rectangle.
Now let us substitute into the formula,


The above expression corresponds to option
F.
Now when we expand the bracket, we obtain,

This also corresponds to option A.
The correct answers are
To find the median we have to put them all in order.
8,8,8,9,14,14,20 then take the middle number, which is 9.
To find the mean, just add all the numbers and divide by the number of numbers lol.
8+8+8+9+14+14+20=81.......81/7=11.6
Median=9
Mean=11.6

P would equal -3/7

<span>c(ad)+x=bd+ad(yz)
step 1:
first we separate x and y , so
x=bd+adyz-cad
Note: i) (yz) can be written as yz
ii) when the term cad comes to right side it becomes -cad, because it is with the addition operation in the left hand side. (it is a general rule of mathematics)
step 2: then we take out the common data from the above equation, so the common term for all terms in the right hand side is 'd',
so, x=d(b+ayz-ca)
step 3: now we need to find d, so
d =x/b+ayz-ca
Note: the term (b+ayz-ca) becomes the divisor of x since it is in the multiplication term on right hand side. so when moving it to left side, it becomes a division operator. (it is also a general rule of mathematics)
so d =x/b+ayz-ca</span>
