The Least Common Multiple of 5, 6, 7, and 9 goes into 5, 6, 7, and 9. The Least Common Multiple of 5, 6, 7, and 9 is 630. If you multiply that by 2, 3, 4, and so on, you get a never-ending set of numbers that go into 5, 6, 7, and 9.
your answer is 52. just subtract: 72-20=52
Answer:
1. 80
2. 63
Step-by-step explanation:
1. 32 divided by 4 = 8. 8 goes into 32 four times. (8+8+8+8=32)
9 times 8 = 72. 9 goes into 72 8 times. (9+9+9+9+9+9+9+9=72)
So we have 8 and we have 72.
There is an addition sign in between 32 divided by 4 and 9 times 8 - So we add 8 and 72.
8 + 72 = 80.
2. So we take 24 times 2.
24 times 2 = 48
then, we take 5 times 3.
5 times 3 = 15
Just as in problem one, we see that there is an addition sign between these two multiplication problems. So, we add them together.
48 + 15 = 63.
HOPE I HELPED.
I’m gonna say c, but I’m not for sure
Let x = 1st positive integer
Let x + 1 = 2nd positive integer
As give, their sum of squares is 841
factor 2 out, 
(x+21)(x-20)
This gives, x=20 and =-21 (neglect the negative value)
So, x = 20
x+1 = 21
So, the two numbers are : 20 and 21
