Approximate √80 by using perfect squares. 80 is between which two perfect squares.​

answer: add the !

step-by-step explanation: then we will answer

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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.
