Joseph uses 44 red beads, 32 white beads, and 64 blue beads to make a necklace. He wants to make 5 necklaces. Which are the three partial products that will be added to find the number of beads that are used to make 5 necklaces? Choose all that apply.

Joseph needs to use:

44 red beads

32 white beads

64 blue beads

to make one necklace.

If now he wants to make 5, then he must multiply by five each one of these quantities, then he will need:

44*5 = 220 red beads

32*5 = 160 white beads

62*5 =  310 blue beads.

Or a total of:

(44 + 32 + 62)*5 = (138*5) = 690 beads.

Where the partial products are:

(44*5) + (32*5) + (62*5)

Of course, there are a lot of other possible partial products, like:

138*5 = 100*5 + 30*5 + 8*5

But we do not have the options, so we can not select the correct ones, so i just gave a general solutions.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

its kind of blurry. can you put a clearer pic?
