expressing/equation: 9x²= 81x
81x + 9x + 2=
9x+81x=90x
90x + 2
Step-by-step explanation:
I cannot suggest anything other than the set of real numbers here, but maybe someone else can provide a better answer. As long as you increase or decrease x (which is a real number) then you will get a real number, or the infinite set of real numbers.
To do this add all the numbers up then divide it by the amount of numbers there are
It looks like the first 3 are because they all are blank x2.5 but the last one would be 8x2.5=20..
