Answer: B - 3(4 + 8) + (2 • 5)

Choice A: 5(9 – 3) + (6 • 2)

We first solve whats inside the parenthesis. This time, we wont do it from left to right. Since 6 and 2 are being multiplied, and 9 and 3 are being subtracted, we will first solve multiplication.

(6 • 2) = 12

New equation is 5(9 - 3) + 12. Now we solve subtraction.

(9 - 3) = 6

New equation is 5 • 6 + 12. Now we solve in order.

5 • 6 = 30

30 + 12 = 42

This means that choice A is NOT it, since it is not 46.

Choice B: 3(4 + 8) + (2 • 5)

Again, we can't solve in order since 2 and 5 are being multiplied, while 4 and 8 are being added. So we solve multiplication first:

(2 • 5) = 10

New equation is 3(4 + 8) + 10. Now we solve addition in parenthesis:

(4 + 8) = 12

Our new equation is 3 • 12 + 10. Now we solve in order:

3 • 12 = 36

36 + 10 = 46

This means that choice B IS correct, since it is 46.

Choice C: 7(3 + 3) + 7

This one is a bit easier, since it only has one in-parenthesis equation. So we solve the equation in the parenthesis and solve in order:

(3 + 3) = 6

7 • 6 = 42

42 + 7 = 49

This means that choice C is NOT correct, since it does not equal 46.

Choice D: 2(10 + 5) + 6

Again, one is easier, since it only has one in-parenthesis equation. So we solve the equation in the parenthesis and solve in order:

(10 + 5) = 15

2 • 15 = 30

30 + 6 = 36

This means that choice C is NOT correct, since it does not equal 46.

Choice B is the correct one, since it equals 46

Hope this helps :)
