Answer 1

4 • 23 = 92 so the correct answer is a  4(20+3).

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

For example, x + y is an expression, where x and y are terms having an addition operator in between.

Expressions can be simplified to form an answer. For example, 3+6-2 is an expression that can be simplified to 7. There are two different ways to simplify arithmetic expressions and algebraic expressions. We use the bracket open division multiplication addition subtraction rule which means the operations are performed in the given manner to simplify them.

For example, 2x+5x results in 7x, whereas 7ab-b is an expression that has two unlike terms, which cannot be added.

Checking for all the options:

option a) 4 (20+3)=4 * 23 = 92

option b) 4 (2 + 13) = 4 * 15 =60

option c) 4 (20 + 30) = 4 * 50 =200

option d) 4 (2 + 3) = 4 * 5 = 20
