Step-by-step explanation:
x2 - 7x + 12
Finding factors of 12
x2 - 4x - 3x + 12
x(x - 4) - 3(x - 4)
(x-4) (x-3) are the factors
Option C is the correct answer
Answer:
108 gadgets
Step-by-step explanation:
We can use a ratio to solve
24 gadgets x gadget
------------------- = ---------------
2.5 hours 11.25 hours
Using cross products
24 * 11.25 = 2.5 *x
270 = 2.5x
Divide by 2.5
270/2.5 = 2.5x/2.5
108 = x
Answer:
LCM: 60
