Answer:
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution

So if the cliff is 225 yard in height and he want to make it down in 5 equall decents
that means that each dessent is 1/5 of 225 or 225/5
225=125 times 5 so if you divied 225 by 5 then you get 125
so each dessent is 125 yards
If there's 100 cookies, of which there are 40 oatmeal raisin and 10 sugar cookies, there are 50 out of 100 cookies which you want. Hence by chance, there is a 50/100, or 1 in 2 chance of you obtaining an oatmeal raisin or a sugar cookie.
Answer:
4
Step-by-step explanation:
Take 1/5 divided by 4/5. In order to divide fractions you take the problem:
(4/5)/(1/5)
Then you flip the second fraction and multiply:
4/5 x 5/1
20/5
4
You could also just divide 4 by one, since the two fractions have the same denominator
