9x^+11
I believe this is the answer
Answer:
The end result is -1/(x + 1)
Step-by-step explanation:
In order to find the answer to this, we first need to factor the denominator. Since it is a quadratic, we try to find number that multiply to the last term (8) and add to the middle term (9). In this case, the numbers 8 and 1 would work. This allows us to use those numbers in parenthesis along with x as a fully factored form.
x^2 + 9x + 8 = (x + 1)(x + 8)
Now that we have this factored we can take the original equation and factor a -1 out of the top.
(-1)(x + 8)/(x + 1)(x + 8)
Since there is an (x + 8) on the top and bottom, we can cancel those.
-1/(x + 1)
Answer:
Betsy uses gold to make the earrings
Step-by-step explanation:
Given:
Amount of gold with Betsy = ten and one half ounces
Amount of gold Betsy used to make earrings = four fifths
To Find:
How much gold is used by Betsy to make earrings = ?
Solution:
Let the quantity of gold used by Betsy to make earring be X
Then
X = four fifths of ten and one half
X =
X =
X =
X=
Reducing the fraction to lower terms and converting into mixed fraction we get,
X=
Xm=x+z
minus x both sides
xm-x=z
undistribute x
x(m-1)=z
divid both sides by (m-1)
.65
13/20
Just simply divide and you get .65
