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.
The range of the function is A
Answer:
perimeter of the garden=2(length+width)
=2(7√13+√13)
=2(8√13)
=16√13
Answer:
hello : (f-g)(x) = -5^x +3x-2
Step-by-step explanation:
(f-g)(x) = f(x) - g(x) = (-5^x-4) - (-3x-2) = -5^x-4 +3x+2
(f-g)(x) = -5^x +3x-2
