Answer: -45
Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here, we have 7 + -12 which is -5.
When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.
Now, we have (-5) (9).
Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.
Therefore, (7 + 12) × 9 = -45.

Answer:
Expressions B, D and E
Step-by-step explanation:
Here, we are to select which of the options is correct.
Let’s put in mind that they bought earn $12 per hour
x represents the number of hours Tina worked this week; the total amount of money she made would thus be x * 12 = $12x
Remembering that she made $46 overtime, the total amount of money she made that we would be $12x + 46
The total amount Tammy made, earning $12 per hour and working for y hours = $12 * y = $12y
The total amount of money both made is thus;
12x + 46 + 12y
= $(12x + 12y + 46)
Now, we have similar expressions in the question;
These are; expression B, expression D and expression E
While expression B is straightforward, the others are not
expression D is gotten by factoring out 12; 12x + 12y + 46 = 12(x + y) + 46
expression E just involved putting what each of the two earned in brackets
