Find x if these are similar:
7 cm, 3 cm, 12 cm, and x cm

i want to say 28

Step-by-step explanation:

this is because 3 times 4 is 12 so i multiplied 7 by 4

1) inverse multiplication

2) Cumulative addition

3) Inverse addition

Step-by-step explanation:

While solving the expression we will mention the statements.

We will solve the left hand side of the given equation to get the right side.

(inverse multiplication)

Now expression becomes

in this expression 1 + 5 = 6 ( cumulative addition)

Now the expression is

6 +(-1 ) = 5 (inverse addition)

So three statements are justifying the solution.

1) inverse multiplication

2) Cumulative addition

3) Inverse addition
