Rob says all numbers have an even number of factors marcia says numbers have an odd number who is correct explain

Step-by-step explanation:

a number that  is a perfect square if it has an odd number of factors.For example 25 is a perfect square then it has odd number of factors 1,5,25. If a number is not a perfect square then it can have an even number of factors.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
