23 over 21 is the right answer
23
----
21
Square would be the best answer
You start counting from 0 onwards:
C = 6
D = 8
Then C x D = 48
So the product CxD is situated at 48 units from 0
║a+9║/7=5
you multiply 7 on both sides which cancel out 7.
now it ║a=9║=35
and now it would be a+9=35 and a+9=-35 then solve it.
35-9 and 9-(-35)= 26 and -44
hope this helped!
