Question

describe how the value of expression a compares to the value of expression b. choose your answer from the dropdown menu.
expression a: (56 + 7) - 42; expression b: 56 + 7
expression a is dropdown with options: 42 greater than, 42 less than, 42 times as large as expression b.

Explanation:

Step1: Calculate Expression A

First, calculate the value inside the parentheses: \(56 + 7 = 63\). Then subtract 42: \(63 - 42 = 21\). So Expression A is \(21\).

Step2: Calculate Expression B

Calculate \(56 + 7 = 63\). So Expression B is \(63\).

Step3: Compare the two values

Subtract the value of Expression A from Expression B: \(63 - 21 = 42\). This means Expression A is 42 less than Expression B.

Answer:

42 less than
