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
:)
*im sorry but I cant see the bottom number but I'll consider it as x
tan 45° = 3/x
x = 3/tan45
x is 3
hope this helps :)
First we have to figure out how much 3 bags cost using the total cost of $8.25
That means. we would do 8.25/3 and 8.25 divide by 3 equals 2.75.
Now we know that each bag costs approximately $2.75
All we have to do now is multiply 2.75 by 4 to get the cost for the total of 4 bags.
4 times 2.75 is exactly 11 dollars, if might change if theres tax.
But, the answer would be 4 bags costs $11.
