Answer:
√a(√a + 2) a - 2√a
----------------- = -----------------
a - 4 a - 4
Step-by-step explanation:
I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:
√a
----------
√a - 2
To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:
√a(√a + 2)
-----------------
a - 4

The correct question is
<span>Mama Mia restaurant used start fraction, 1, divided by, 2, end fraction of their mozzarella cheese making pizza and the remaining 64 ounces making pasta.
How many pounds of mozzarella cheese did Mama Mia start with?
Let
x---------------> total </span>ounces of mozzarella
<span>
we know that
making pizza-----------> (1/2)*x------> x/2
therefore
making pasta-------> [x-x/2]--------> (2x-x)/2-----> x/2
making pizza=making pasta=x/2
(x/2)=64---------------> x=64*2-----------> x=128 ounces
remember that
1 ounces----------------> 0.0625 pounds
then
128 ounces*0.0625=8 pounds
the answer is 8 pounds

Answer:
gallon.
Step-by-step explanation:
We have been given that Pheng-Xu drinks 1 cup of milk every day for lunch.
1 week = 7 days
2 weeks = 2*7 days = 14 days.
First of all, we will find number of cups needed by Pheng-Xu in two weeks by multiplying 1 by 14.
1 US fluid gallon equals 16 cups of milk.
Now, we will divide 14 by 16 to find gallons of milk needed by Pheng-Xu.
Therefore, Pheng-Xu needs gallon of milk.
