Write an algebraic expression for each phrase?

Don’t know if those are right also

Answer & Step-by-step explanation:

1) 4x

2) y-8

3) 6/x

4) 12-y

5) y+9

6) 5^2

7) x^4

8) 9+n

9) 64-y

10) 12/n

11) x^2/7

12) x-8=22

13) 2a-b^2

14) 12-ab

4xy - 86 / x12 - y9 + y5^2x^49 + x64 - y12 / xx^2 / 7x - 8 = 222a - b^212 - ( a × b )

Hopefully this helped!

 In any arithmetic sequence, each term is equal to the previous term plus the common difference. 

 Thus, the second term is equal to the first term plus the common difference. In this sequence, the second term, 5, is 3 less than the first term, 8. 

 Therefore, the common difference is -3.
