Answer 1

Answer:

B.) a+a+a+a+b+b

Explanation:

Given the expression 4a + 2b

We are to find the equivalent expressions

4a means the sum of 'a' in four places

4a = a+a+a+a

2b means the sum of 'b' in two places

2b = b+b

Combining both expressions

4a + 2b = a+a+a+a+b+b

Hence the correct option is B
