Answer 3

Simplifying Expressions:

a) 4a + 90a To simplify the expression 4a + 90a, we can combine the like terms. When adding or subtracting terms with the same variable, we add or subtract the coefficients while keeping the variable the same. In this case, both terms have the variable 'a', so we can add the coefficients: 4a + 90a = 94a b) 86b - 77b Similarly, to simplify the expression 86b - 77b, we can combine the like terms by subtracting the coefficients: 86b - 77b = 9b c) 209m + m For the expression 209m + m, we can combine the like terms by adding the coefficients: 209m + m = 210m d) 302n - n Lastly, for the expression 302n - n, we can simplify by subtracting the coefficients: 302n - n = 301n These are the simplified forms of the given expressions.
