Rebecca says that all monomials with the same degree are like terms explain rebecca's error

This not true because the monomial may have the same degree, but different variables. So, Rebecca forgot to include the variables and the number variables when determining her answer. Keep in mind the variable also determines the like terms. Ex: 5y^2 and 5x^2 aren't like terms just because the degrees are the same. Good luck.

step-by-step explanation:

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":

we must add 15 to both sides of the equation:

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

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