D

Step-by-step explanation:

First, start with the ones column. 2*9 is 18, so write the 8 below and carry the 1 into the tens column. Now, we do 9*7 plus the 1 we carried, so that makes 64. The first row under the line should be 648. Next, annex a zero under the number 648 in the ones column. Now we move to the tens. 1*2 is 2. 1*7 is 7. The number under 648 should be 720. Now, we add 648 and 720. 648+720 is 1,368. 1,368 is our final product, which makes the answer D. I'm sorry if this seemed confusing (it's a bit hard to explain in words), but I hope it helps!

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
