The figure is reflected across line m and then reflected across line n. what is the resulting transformation?

We know that when a figure is reflected across a line that we obtain a mirror image of the figure at the opposite side of the line and at a same distance from the line as it was before the reflection transformation.\

Hence, here we are given a star shaped figure which is to be reflected first across the line m and then across the line n.

So, the series of reflection transformation is applied to it.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
