the answer is C.

Step-by-step explanation:

C.) 2x^2-11x+23=0

Step-by-step explanation:

2x^2+x+3=4(3x-5)

Distribute the 4 on the right side

2x^2+x+3=12x-20

Move everything to one side

2x^2+x+3-12x+20=0

Simplify

2x^2-11x+23=0

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
