40 points! linda wants to buy 2 sweaters and a pair of sunglasses at wild orchids. each sweater costs the same amount. the sunglasses cost $12. which equation can be used to find the total cost of her purchases?

a. 12s - 2 = c

b. 12s + 2 = c

c. 2s + 12 = c

d. 2s - 12 = c

You would need to multiply the cost of one sweater by 2 to get the total cost of the sweaters, then add that to the price of the sunglasses.

The equation would be: C 2S + 12 = C

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

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.
