(x+12)^2=(x+12)(x+12) = x^2 +12x + 12x + 144
= x^2+24x+144

Here's our expression: 
We will follow the order of operations and begin by solving everything in parentheses. 
Next, we solve the exponents. 
Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. 
Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction. 
Answer:
It means turning 180 degrees to the left
Step-by-step explanation:
Answer: In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system
(-6x-2)-(-3x+5)= -24x+14
-6x-2+3x-5=-24x+14
-3x-7=24x+14
