The statement is an equation which is written in text form or in words. when we write it as an equation it will be:
squares of w and x is equal to w² and x² so, their sum means they are going to add.
3 + (w² + x²) = 32
three plus the sum of w² and x² is 32.
when we describe or write quantity with an equal sign it makes an equation.
