Step-by-step explanation:
cubing both sides (p+1)^3= (7)^3
=> p^3+1/p^3+ 3(p+1/p) = 343
=> p^3+ 1/p^3 + 3(7)= 343
=> p^3+1/p^3= 343-21
=> p^3+1/p^3= 322
hope it helps
Answer:
-7/2 or -3.5
Step-by-step explanation:
h = 20
= h = 35 = h = 70 (2h) (2h)
19h = 35h = 70(2h)(2h)
16h = 70(2h)(2h)
-70 = 20h
-7/2 = h
-3.5 = h
Answer:
there is only one solution
3x - 1 = 2x
x - 1 = 0
x = 1
Answer:
x = ( k+c)/5
Step-by-step explanation:
5x - c = k
Add c to each side
5x -c+c = k+c
5x = k+c
Divide by 5
5x/5= ( k+c)/5
x = ( k+c)/5
