Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
The size of the next smaller scale wil about 1.464.
The scale factor represents the change between the different sizes. We multiply by it to increase and divide by it to reduce.
1.772 / 1.21 = 1.464
