To simplify the fraction, we need to rationalize the denominator by multiplying the numerator and denominator by the conjugate.
The conjugate is the same thing as the denominator with a plus sign instead of a minus sign.
(sqrt(2) + start(5))^2/((sqrt(2) - start(5))(sqrt(2) + start(5)))
FOIL the top and bottom.
The answer is -(7+2sqrt(10))/3
Answer:
All are correct
Step-by-step explanation:
If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.
