Question

1. which expression has the same value as 4(7 + 5)

a. 28 + 35
b. 11 + 9
c. 28 + 20
d. 12 + 4

Explanation:

Step1: Calculate \(4\times(7 + 5)\)

First, solve the expression inside the parentheses: \(7+5 = 12\). Then multiply by 4: \(4\times12=48\).

Step2: Calculate option a: \(28 + 35\)

\(28+35 = 63\), which is not equal to 48.

Step3: Calculate option b: \(11 + 9\)

\(11+9 = 20\), which is not equal to 48.

Step4: Calculate option c: \(28 + 20\)

\(28+20 = 48\), which is equal to the result of \(4\times(7 + 5)\).

Step5: Calculate option d: \(12 + 4\)

\(12+4 = 16\), which is not equal to 48.

Answer:

c. \(28 + 20\)
