Answer:
3½÷7=½ liters
Step-by-step explanation:
Change 3½ into a improper fraction.
3½=7/2
7/2÷7=
keep change flip
7/2×1/7=½
The answer to the equation would be 14

Make it more general, and see what happens when you try to reduce the exponent of
x in the following integral:
Now, integrate it by parts:
where
So after one iteration, the exponent of
x was decreased by one unit.
The question is:
after how many iterations will the exponent of x equals zero? After exactly
k iterations, of course.
Therefore, for
k = 7, you have to apply integration by parts
7 times, to get rid of that polynomial factor. Then, there will be one last integral left to evaluate:
But this one doesn't need to be evaluated by parts. You can directly write the result:
Shortly, for the integral
you have to apply integration by parts
7 times (not
8 times).
I hope this helps. =)

Your answer would be C
if triangle efg is equal to hjk then it will still be equal the opposite way. The symmetric property tells us that both sides of the equal sign are equal no matter what side they are on.
