B = 1/4c + 14
d = 5/4c - 2
b = d
1/4c + 14 = 5/4c - 2
1/4c - 5/4c = -2 - 14
-c = - 16
c = 16 <=== chris got 16 correct
b = 1/4c + 14
b = 1/4(16) + 14
b = 4 + 14
b = 18 <=== Brian got 18 correct
d = 5/4c - 2
d = 5/4(16) - 2
d = 20 - 2
d = 18 <=== damien got 18 right also

Answer:
3√2
Step-by-step explanation:
In this question, we are asked to get the value of √ ( x²-y² ), while the value of x² and y² are given to be 33 and 15 respectively.
Hence, x² =33 and y² = 15.
Putting the values of x² and y² in the above expression we get,
√ ( x²-y² ) = √ ( 33-15) = √18 =3√2. (Answer)
