20. write and evaluate two equivalent numerical expressions using brackets or braces that show the distributive property.
Answer
Explanation:
Step1: Define the distributive property
The distributive property is (a(b + c)=ab+ac). Let (a = 2), (b=3), (c = 4).
Step2: First equivalent expression
The first expression using the distributive - form is (2\times(3 + 4)). [2\times(3 + 4)=2\times7=14]
Step3: Second equivalent expression
The second expression using the expanded - form is (2\times3+2\times4). [2\times3+2\times4 = 6 + 8=14]
Answer:
The two equivalent expressions are (2\times(3 + 4)) and (2\times3+2\times4), and their value is 14.
