Use properties of real numbers to write $- r ( s - 2 )$ without parentheses.
A) $- 2 r + 2 s$
B) $- r S + 2$
C) $rs + 2 r$
D) $- r s + 2 r$
E) $- rs- 2 r$

We can use the distributive property to write the expression as:
$-r(s-2) = -r \cdot s + r \cdot 2$
Then, using the commutative property, we can write:
$-r \cdot s + r \cdot 2 = 2r - rs$
Therefore, the correct choice is D.

Use Properties of Real Numbers to Write −r(s−2)- r ( s - 2 )−r(s−2)
