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 =
Answer: C) log₄ 84
<u>Step-by-step explanation:</u>
The rule for condensing (combining) log expressions that are added is MULTIPLICATION
log₄12 + log₄7 = log₄(12 × 7) = log₄ 84
