I have a math test please give me the right answer!!

Answer 1

225

Explanation:

(r - 3)³ + r² if r = -3 and s = -4

(-3 - 3)^3 + (-3)^2

(-6)^3 + (9)

(-6 x -6 x -6) + 9

-216 + 9

-207

Answer 2

-207

Explanation:

Using r= -3, we can substitute r in the whole equation as (-3) which gives you: ((-3)-3)^3 +(-3)^2. Now you can calculate these values in a step by step manner. (-6)^3 +9 then to -216 +9 which brings you to the answer of -207.
