Answer:
A sqrt(x+2) - sqrt(x)
Step-by-step explanation:
2
--------------
sqrt(x) + sqrt(x+2)
Multiply top and bottom by sqrt(x) - sqrt(x+2)
2 sqrt(x) - sqrt(x+2)
------------------------ * --------------------------
sqrt(x) + sqrt(x+2) sqrt(x) - sqrt(x+2)
FOIL the denominator
2 (sqrt(x) - sqrt(x+2))
------------------------------
sqrt(x^2) - sqrt(x) sqrt(x+2) + sqrt(x) sqrt(x+2) - sqrt(x+2)^2
2 sqrt(x) - 2 sqrt(x+2)
------------------------------
x - (x+2)
Distribute the minus sign
2 (sqrt(x) - sqrt(x+2))
------------------------------
x - x-2
2 (sqrt(x) - sqrt(x+2))
------------------------------
-2
Cancel the 2 in the top and bottom
(sqrt(x) - sqrt(x+2))
------------------------------
-1
Distribute the -1
sqrt(x+2) - sqrt(x)
Answer:
x-35.75=40.00
Step-by-step explanation:
Let's use <em>m </em> as our variable.
So Marlen went to the mall and spent $35.75 on shoes. When she got home she had $40.00 in her purse.
An equation to represent this is : x-35.75=40.00
If you are interested in the value of x it is $75.75
Expanding the right side:-
5x - 4 = 5x - 15 + 11
5x - 4 = 5x - 4
left side = right side so there are infinitely many solutions
Answer:
180-65=115
Step-by-step explanation:
Straight line always measures 180 degrees, take 180 and subtract 65 thats your answer.
