we get the union of the given expression by simplifying it as (-∞, 9).
We given the expression that:
(-∞, 5] U [-13, 9)
we need to simplify the expression and tell the union of the expression.
We get that:
After doing the union, we will combine all the numbers.
So, we have
(-∞, 5] U [-13, 9) = (-∞, 9)
now we will find the intersection for the same expression. so, we will get the intersection as:
(-∞, 5] ∩ [-13, 9) = [-13, 5]
therefore we get the union of the given expression by simplifying it as (-∞, 9).
