Evaluate the following expressions. Let a = 5, b = -4, and c = 10. 12. ab =

13. b + c =

14. c/5 =

15. C - 5 =​

-20, 6, 2, 5

Step-by-step explanation:

a = 5, b = -4, c = 10

12. ab = 5(-4) = -20

13. b + c = -4 + 10 = 6

14. c/5 = 10/5 = 2

15. c - 5 = 10 - 5 = 5

12. -20

13. 6

14. 2

15. 5

Step-by-step explanation:

12. ab

a multiplied by b

a= 5 , b = -4

ab= 5 x (-4)

ab = -20

13. b + c

b = -4 ,c = 10

b + c = -4 + 10

b + c = 6

14. c / 5

c = 10

c / 5 = 10 / 5

c / 5 = 2

15. c - 5

c = 10

c - 5 = 10 - 5

c - 5 = 5

the answer would be c:   ax + b = ax + c
