Let y = 2g + x^2 and g = 4x + 1.
If g^2 = 625, then which of the following can be a value of 2y + 3g?	Choose the correct choice from the following choices
A) 100
B) 130
C) 141
D) 142
E) 247
800score Official Solution:   First note that g can either be 25 or -25. We are going to have to use both to find all solutions before we can choose a final answer. We begin by substituting g = 25 and then g = -25. If g = 25, then x = 6. If g = -25, then x = -26/4. Since all of our solutions are whole numbers, we can dismiss -26/4. We use g = 25 and x = 6 to determine the value of y: y = 2(25) + 36 = 86. Finally, we substitute the values for y and g into the last expression to determine its value : 2(86) + 3(25) = 172 + 75=
