Question

. 4. If m = -100, find the value of m2 - 2m - 1000.
5. If r = -10, find the value of r3 - 5(r-5).​

Answer 1

Answer:

question 4=9200

question 5=925

Answer 2

Answer:

Here is your answer...

Step-by-step explanation:

4. m²- 2m - 1000 = -(100)² - 2(-100) - 1000

                            = 10000  + 200 - 1000

                            = 9000 + 200

                            = 9200

5.  r³ - 5(r-5) = (-10)³ - 5(-10 - 5)

                    = -1000 - 5(-15)

                    = -1000 + 75

                    = -925
