There are many pairs you could do, but I'm going to choose this one:
(-3a)(9a)

You can multiply them together, and get (that's how you know if they are factors):
(-3a)(9a) = -21a^2

Hope this helped!

If twelve pounds of nails cost $3.84 what is the unit cost A) 32c B) 28c C) 23c D) 18c
aalyn [17]

Answer:

Option A) 32c

Step-by-step explanation:

we know that

To find the unit cost, divide the total cost of twelve pounds by twelve pounds

so

\frac{\$3.84}{12}=\$0.32

Remember that

1$=100 cents

Convert dollars to cents

\$0.32=0.32*100=32c

therefore

The cost of one pound of nails cost 32 cents

Find the means of these numbers 3,7,2,9,4,7,3,7,5,2
Sholpan [36]

The "mean" of a group of numbers is also called their "average".

To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.

Step #1:  Addum up:  3+7+2+9+4+7+3+7+5+2 = 49

Step #2:  Count the number of items on the list:  I count 10 .

Step #3:  Divide the sum by the number of items on the list.

                 49 / 10  =  4.9

The mean (average) of the numbers on that list is  4.9 .
