Answer:

12y + 5x - 15

Step-by-step explanation:

7y + 4x - 10 + 5y - 5 + x

7y + 5y = (7 + 5)y = 12y

12y + 4x - 10 - 5 + x

4x + x  = 4x + 1x = (4 + 1)x = 5x

12y + 5x - 10 - 5

- 10 - 5 =  - (10 - 5) =  - 15

= 12y + 5x - 15

If p+1/p - 7 then find the value of p³+1/p³ ​
ankoles [38]

Answer:

322

Step-by-step explanation:

We have,

a^3+b^3=(a+b)^3-3ab(a+b)

p+1/p=7

Now,

p^3+1/p^3=(p+1/p)^3-3*p*1/p(p+1/p)

               =7^3-3(7)=343-21=322
