rachel breaks up a large array into two smaller arrays. the two smaller arrays show 3 times five and 4 times 5. what was the large array that rachel started with?

So the bigger array is 12 and 25

Step-by-step explanation:

Let's do a multiplication of this array first and Know it's result.

3 times five and 4 times 5. = (3*5) and (4*5)

= 15 and 20

Multiplying further gives us

= 15 * 20=300.

So to combine to get the bigger array.

We must get back 300 as the result of our product.

Let's multiply the row(x) with the row(x)

And the column (y) with column(y)

3 times five and 4 times 5.= 3*4 and 5*5

So the bigger array is 12 and 25

To check.

12*25 = 300

Proved.

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
