Question

Which statements are true for the following expression? 13 · (2 + 9) Check all that are true. a) The second factor is itself the sum of two terms. B)The solution is the product of two factors. C)The solution is the quotient of two factors. D)The solution is the sum of two terms. The first factor is itself the sum of two terms.\

Answer 1

a) b) is your answer

Answer 2

Explanation:

The given expression is

`13(2+9)`

We can describe this expression as the product between a 13 and the sum of two 2 and 9, that is, the second factor is a sum of two terms, this means option A is a true statement.

As a product, the solution of this expression is the solution of that product, however, we first have to sum both terms inside the parenthesis, like this

`13(2+9)\\13(11)=143`

Therefore, B is also a true statement, because it's true that the solution is the product of the expression.

On the other hand, other options are completely wrong, because the expression is not a quotient, and the expression inside the parenthesis is not a difference, neither the solution is the sum of two terms.

Therefore, the right statements are A and B.
