I will give 30 to who ever will figure this out please helps it’s due in the morning

1. 13x+4        2.   -6x-7      3.  -8x-7      4.   7x+3/x+2     5.  -3        9x2+24x+15/3x+2   6.

Step-by-step explanation:

number 4 is a fraction answer so put 7x+3 at the top x+2 at the bottom

number 6 is a fraction answer so 9x2+24x+15 at the top rest at the bottom

also, 2 is the exponent for number 6

sorry, I didn't do number 7 it's kinda complicated.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

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.
