Question

1. how many terms are in: 4r + 2d - 5

Explanation:

Step1: Define a term in an expression

In an algebraic expression, a term is a single number, variable, or the product of a number and variable(s), separated by addition or subtraction signs.

Step2: Identify terms in \(4R + 2D - 5\)

• The first term is \(4R\) (product of 4 and \(R\)).
• The second term is \(2D\) (product of 2 and \(D\)).
• The third term is \(- 5\) (a single number, we can also think of it as \(-5\) which is a constant term).

So we count these terms: \(4R\), \(2D\), and \(-5\).
