Step-by-step explanation:
simple
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
Then a is Half of 45 wich is 22.5 I believe.
The subtracton property of equality allows you to subtract the same amount from both sides of an equation without changing the truth of the equation.
