Answer:
x^3 + 1/x^3 = 488
Step-by-step explanation:
- x^2 + 1/x^2 = 62
- x^2 + 1/x^2 + 2 = 64
- ( adding 2 in both sides )
- (x + 1/x ) ^2 = 64
- x + 1/x = 8
now,
- ( x+ 1/x ) ^ 3 = 512
- x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
- x^3 + 1/x^3 + 3 ( 8 )
- ( since x + 1/x = 8 )
- x^3 + 1/x^3 + 24 = 512
- x^3 + 1/x^3 = 488
hence, we got x^3 + 1/x^3 = 488
Answer:
if its A PACK then it would be 3 dollars but this is absolutely wrong i already know it LOL
The identity property of addition; if you add 0 to any numerical or non-numerical value, that value stays the same, or keeps its identity.
4x^2 cannot be combined with the others if you are using addition or subtraction. However, the other three answers can be combined:
(-3x) + x + 11x = (-3x) + 12x = 9x.
or
11x -x -(3x) = 10x -3x = 7x.
Your answer is 4x^2
Hope this helps!
