The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4
Answer:
750
Step-by-step explanation:
total cost = 650
total selling = 210/3 x 20 = 70 x 20 = 1400
total profit = 1400 - 650 = 750
Answer:
2
Step-by-step explanation:
2 (x-2)=8 equal to 2x-4=8, put -4 to the other side by subtracting 4 on both sides once you do you get 2x=4 so 4 divided by 2 equals 2.
If Carly had more DVDs than Rob then you would subtract her amount away from the total. 42-4=38
