Does anyone know what this n does in the equation?

(x + 5 < 4) ∩ (x - 3 > -6).

The symbol ∩ signifies the intersection of the left operand and the right operand. Here, it means "and", as it often does.

Step-by-step explanation:

The solution to the left inequality is x < -1.

The solution to the right inequality is x > -3.

The intersection symbol (∩) means you are interested in the interval where these solutions overlap—the intersection of the solutions: -3 < x < -1; (-3, -1) in interval notation.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
