GIVING BRAINLIEST!!!!

Select the statement that describes the following expression 6 x (2 + 7) − 9.

A) 6 times the sum of 2 and 7, then subtract 9
B) 6 times the product of 2 and 7, then add 9
C) 6 times the difference of 2 and 7, then subtract 9
D) 6 times the sum of 2 and 7, then add 9

Answer 1

Answer:

A) 6 times the sum of 2 and 7, then subtract 9

Step-by-step explanation:

At the end of the given expression, there is a " - 9", which means that the 9 is getting subtracted. From this you can cancel out answer choices B and D because they add 9.

In the expression, there is a (2 + 7), which means that the 2 and the 7 are being added together, producing a sum. That cancels out answer choice C, leaving choice A.

Answer 2

Answer:

Step-by-step explanation:

Order of operation rules require that we do all work inside parentheses first, and then multiplication/division, and only then addition and subtraction.

We evaluate (2 + 7) first, obtaining 9, and then have 6·9 - 9.

This multiplication must be done before the subtraction, so we get:

54 - 9 = 45     This corresponds to Answer A.
