Answer:
The third one
Step-by-step explanation:
You would first mark -2 on a graph then the circle would be open because the sign is just greater than, then the arrow would be pointing to the right, because that is the way your equation shows it
Factorize x²+7x+12 ===> (x+3)(x+4)
Factorize x²-3x-28 ===> (x-7)(x+4)
4x + 12 can be written====> 4(x+3)
Then the question could be written as follows:
[(x+3)(x+4) / (x-7)(x+4) ] / 4(x+3) = [(x+3)(x+4) / (x-7)(x+4) ].[4(x+30]
After simplification you get 1 / 4(x-7)
When you have two unit prices for two comparable items, you have to convert one of the prices to the other one.
