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

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
