Write the sets of points from -2 to 5 but exluding 2 and 5 as a union of intervals

we are given

to write the sets of points from -2 to 5 but excluding 2 and 5 as a union of intervals

so, first interval is

-2 to 2 by excluding 2

Second  interval is

2 to 5 by excluding 2 and 5

now, we can find total interval

we get

[-2,2) ∪ (2,5)..............Answer

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
