Evaluate the expression for r= -3 and s = 5
3r/ s^-2
A. -225
B. -75
C. 75
D. 225
Before we proceed with evaluating the expression, let's simplify it first.
Given: r = -3 and s = 5
So, substituting these values into the expression:
3r/ s^-2
= 3(-3)/ (5^-2)
= -9/ (1/25)
= -9 * 25
= -225
The evaluated expression is -225.
Therefore, the correct answer is A. -225.
