Answer:
80/3
Step-by-step explanation:
30 can be also written as 30/1
30/1*8/9
30*9=240
1*9=9
Then you simplify.
Both 240 and 9 can be divided by 3.
80/3
I think... J because
x + 1 / x^3 - x
Factor out x from the expression
x + 1 / xx(x^2 - 1)
Use a^2 - b^2 = (a - b)(a + b) to factor the expression
x + 1 / x • (x - 1) • (x + 1)
Reduce the fraction with x+ 1
1 / x • (x - 1)
Distribute x through the parentheses
1 / x^2 - x
:)
X+4x=35-20. 5x=35-20. 5x=15. X=3
