i need help pls i need to put my grades up before the end of the semester 20 pionts for who ever answers have a hood night from kentucky

Step-by-step explanation:

a + 2 + a+2 + a + 2 = 24              Combine the left

3a + 6 = 24                                  Subtract 6 from both sides.

3a = 24 - 6                                   Combine

3a = 18                                         Divide both sides by 3

3a/3 = 18/3

a = 6

1.

3a + 6 OR 3(a + 2)

2.

a = 6

Step-by-step explanation:

1.

(a + 2) + (a + 2) + (a + 2) = a + a + a + 2 + 2 + 2

= 3a + 6 or 3(a + 2)

2.

24 = 3a + 6

24 - 6 = 3a

18 = 3a

18/3 = 6

a = 6

sorry if I didn't show my working well enough

answer: ur v dumb

step-by-step explanation:

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.
