Parentheses are used to identify which numbers you should add,multiply .ect first. So If i had
12-(3+1)=x
then you would want to solve 3+1 before you subtract 12.
The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.
So, we can make the equation
. We need to find b, and put b in.
To find b, put in the numbers of y and x.

Solve for b:

Now replace b in the original equation with 12 and that will be the answer:
The answer is
.

Answer:
46,303
Step-by-step explanation:
12789+9324+9324+1078+12789+999= 46,303
If "x" is a multiplication sign:
-3 * 98 + 193 =
-294 + 193 =
