Top:
x / (x + 1) - 1 / x
= [x^2 - (x +1)] / x(x+1)
= (x^2 - x - 1 ) / x (x+1)
Bottom:
x / (x + 1) + 1 / x
= [x^2 + (x +1)] / x(x+1)
= (x^2 + x + 1 ) / x (x+1)
Now you have:
(x^2 - x - 1 ) / x (x+1)
----------------------------
(x^2 + x + 1 ) / x (x+1)
= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )
= (x^2 - x - 1 ) /(x^2 + x + 1 )
Answer:
x^2 - x - 1
---------------------
x^2 + x + 1
Answer:
No Solution
Step-by-step explanation:
Expand:
Add 5 to both sides:
Subtract 4x from both sides:
No solution as this is false.
I think the answer is 52 cm. If you add all the numbers and find out the two missing numbers you will get 52. ( if I’m sorry so how, I’m sorry :))
The answer would be the first phrase.
3x is 3 times x, and +4 is the sum of 3x and 4.
Step-by-step explanation:
Commutative means a + b = b + a
So, 4x + 3 = 3 + x
Associative means a + (b + c) = (a + b) + c
So, 6 + (9 + 7) = (6 + 9) + 7
Distributive means expand the bracket a * (b + c) = a*b + a*c
So, (4x + 3y + 2z) * 7 = 4x*7 + 3y*7 + 2z*7
Commutative is a + b = b + a
So, 15a + 15b = 15b + 15a
