Answer:
9abc(ac² - 3)
Step-by-step explanation:
<u>Given polynomial:</u>
<u>Factors of the terms:</u>
- 9a²bc³ = 3*3*a*a*b*c*c*c
- 27abc = 3*3*3*a*b*c
<u>Common factors of the above: </u>
<u>So the answer:</u>
- 9a²bc³ -27abc = 9abc(ac² - 3)
Answer:
A
Step-by-step explanation:
5 is 50/1000, and 1/2% is equal to 5/1000
Y = 3x - 8
Because y = mx + b, where m is the slope and b is the y-intercept, just substitute the two numbers.
How many different three colour flags (tricolors) can be designed using
green, blue, red, yellow and black stripes if all three colours must be
different?
6P3 = 6!/(6 - 3)! = 6!/3! = (6 x 5 x 4 x 3 x 2 x 1)/(3 x 2 x 1) = 720/6 = 120 flags.
How many of them contain a red stripe?
The remaining two colours can be arranged in 5P2 = 5!/(5 - 2)! = 5!/3! = (5 x 4 x 3 x 2 x 1)/(3 x 2 x 1) = 120/6 = 20ways
The red stripe can arranged in 3 ways
Therefore, number of flags having red stripe is 20 x 3 = 60 flags.
