Question

Evaluate the expression when m = 63 and n = 45

Answer 1

The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.

What is an expression?

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

Given the following variables:

• m = 63.

• n = 45.

Substituting the given variables into the given expression, we have;

Expression = (3m - n)² + 4m.

Expression = (3(63) - 45)² + 4(45).

Expression = (189 - 45)² + 180

Expression = 144² + 180

Expression = 20,736 + 180

Expression = 20,916.
