The LCD is x^2+3x+2 = (x+2)(x+1)
The goal is to get each fraction to have the denominator be equal to the LCD
Afterward we can add the fractions
x/(x^2+3x+2) + 3/(x+1)
x/((x+2)(x+1)) + 3/(x+1)
x/((x+2)(x+1)) + (3(x+2))/((x+2)(x+1))
(x+3(x+2))/((x+2)(x+1))
(x+3x+6)/(x^2+3x+2)
(4x+6)/(x^2+3x+2)
--------------------------------------------------
Final Answer: 4x+6
Note: you can factor 4x+6 to get 2(2x+3)
Answer:
3030
Step-by-step explanation:
2/10 are on the first book. 7/10 are on the second book. This means 1/10 is on the third book. 1/10 of the stamps is 303 stamps. Therefore, the total number of stamps are 3030.
I dont know if I'm right or not but I believe the answer is b, because you cant solve for x with only these numbers.
Answer:
11 hours
Step-by-step explanation:
The number of machines working in the factory = 6 machines
Decreasing it by a factor of 2 =
6 ÷ 2 = 3 machines.
Hence:
If 6 machines complete a big order = 22 hours
3 machines = x hours
Cross Multiply
6 machines × x hours = 22 hours × 3 machines
x hours = 22 hours × 3/6
= 66/6
x = 11 hours
Therefoee, it would take 11 hours to fill the order if the number of working machines decreased by factor of 2.
