This is because we want to avoid having negative numbers under the square root. So we make the radicand to be 0 or larger.
The +1 at the end doesn't affect the domain.

Your answer 493145
I simplify it and got 5x^2+z+6
Step-by-step explanation:
(4x2 – 2x+8)+(x² + 3x - 2)v=5x^2+z+6
The equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)
Let l be the original length of the pool.
Since the length of the pool is increased by 3.7 m, the new length L = l + 3.7.
Also, the area of the pool A = 205.85 square meter and it is a rectangle with width, W = 11.6 meters,
So, A = LW
Substituting the values of the variables into the equation, we have
A = LW
205.85 = (l + 3.7)11.6
So, the equation that can be used to determine the original length of the pool is 205.85 = 11.6(l + 3.7)
