Tabitha has 5 music files, each with 9 songs in it. She is dividing the songs into 7 groups. If each of group will have the same number of songs, how many songs will be left over?

The amount of songs that will be left over is 3.

Step-by-step explanation:

First, you have to multiply the number of music files for the number of songs in each file to find the total amount of songs that Tabitha has:

5 music files*9 song in each file= 45 songs

Now, that you know that she has 45 songs and as you know that she is dividing them in 7 groups that will have the same number of songs, you have to divide the number of songs by the number of groups:

45/7=6.42

So, this means that she will have 7 groups with 6 songs in each one which would be equal to 42 songs as 7*6=42. Finally, to find the amount of songs that will be left over, you have to subtract 42 songs from the total amount of songs that Tabitha has:

45-42=3

According to this, the answer is that the amount of songs that will be left over is 3.

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
