Answer:
a. Jake told the negative value of the expression which cannot be equivalent to the original expression.
b. 10 -
g
Step-by-step explanation:
a. The given expression is: 
Multiplying through out by -, we get:
which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.
b. 

Hence, the answer.
10.75 is the radius for cylinder
x = -9
-3x when x is 3 would be -3(3) = -9
Let's say side length is s.
s*s = 500, so s = √500.
4 sides needed, total length thus 4*s.
4√500 ≈ 89.4
