Which expression can be written as 5 * (2+7)

5 * 2 + 7
5 - (2+7)
(5 * 2) + (5 * 7) THIS ONE
(5 + 2) + (5 + 7)

Yes, the distributive property

Oh, my clowny friend, it seems like you've stumbled upon a math problem! Let's see which expression can be written as 5 * (2+7).

5 * 2 + 7? Nah, that's not quite it. We're multiplying the first number by 2, but not the whole expression inside the parentheses.

5 - (2+7)? Nope, this one involves subtraction, but we want multiplication!

(5 * 2) + (5 * 7)? Bingo! You've found it! This expression is equivalent to 5 * (2+7). We multiply 5 by 2, and 5 by 7, and then add them together. Aren't you a math whiz?

(5 + 2) + (5 + 7)? Ah, close but no cigar! This expression involves addition, but we're looking for multiplication. Keep those equations coming!

The expression that can be written as 5 * (2+7) is (5 * 2) + (5 * 7).

To determine which expression is equivalent to 5 * (2+7), we need to simplify each expression and see which one matches the given expression.

Let's simplify each expression:

Expression 1: 5 * 2 + 7
To simplify this expression, we perform the multiplication first: 5 * 2 = 10. Then we add 7, resulting in 10 + 7 = 17.

Expression 2: 5 - (2+7)
In this expression, we have to perform the addition in the parentheses first: 2 + 7 = 9. Then we subtract 9 from 5, resulting in 5 - 9 = -4.

Expression 3: (5 * 2) + (5 * 7)
To simplify this expression, we perform the multiplications first: 5 * 2 = 10 and 5 * 7 = 35. Then we add the two results together: 10 + 35 = 45.

Expression 4: (5 + 2) + (5 + 7)
Here, we have to perform the additions first: 5 + 2 = 7 and 5 + 7 = 12. Then we add the two results together: 7 + 12 = 19.

Out of the four expressions, only the third expression, (5 * 2) + (5 * 7), simplifies to 45, which is equal to 5 * (2+7). Therefore, the correct answer is (5 * 2) + (5 * 7).
