Answer:

Step-by-step explanation:
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
I think its c. if you get it wrong im sorry if you get it right tell me
X (unknown number at first is 28) is the number 28.
28/7=4. 2(28) divided by 7= is also 56 divided by 7.
Which is 8. 8 is the final answer.
