6 combinations

Step-by-step explanation:

You could have a total of 6 combinations.  2 shirts, and 3 pants 2 x 3 =6

                - shorts                                               - shorts

1 red shirt - slacks                            1 blue shirt - slacks

Real zeroes states that where a graph crosses or touches the x-axis or we can say that

a real zeroes of a function is a real number that makes the value of the function equal to zero.

Given:  

Let f(x) =

then, by the definition of real zeroes we have;

f(x) = 0 to find x;

=0

Add 7 to both sides of an equation we get;

=0+7

Simplify:

=7

or

Add 12 to both sides of an equation;

Simplify:

x=

therefore, the real zeroes of a given function is;
