Rewrite the expression ab dc ef such that each variable is replaced by a different non- zero digit and the value of expression is 1. (the answer may not be unique.)

ab dc ef is replaced by 12 43 56

Step-by-step explanation:

ab dc ef are replaced by the position they take when writing in an alphabetical order. a is 1, b is 2, c is 3, and so on.

12 43 56

and

56 - 43 - 12 = 1

i do not know the answer

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.
