Choose any four consecutive even numbers. (for example: 6, 8, 10, 12). multiply the two middle numbers together. (e. g. 8 x 10 = 80) multiply the first and last numbers. (e. g. 6 x 12 = 72) now subtract your second answer from the first. (e. g. 80 - 72 = 8) try it with your own numbers. why is the answer always 8?

Step-by-step explanation:

let the consecutive even numbers be  2n-2,2n,2n+2,2n+4 where n>0 and n is an integer.

2n(2n+2)-(2n-2)(2n+4)

=4n²+4n-(4n²+8n-4n-8)

=4n²+4n-4n²-8n+4n+8

=8

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
