Ab+ac=a(b+c)
a is a common factor to both
find greatest common factor
factor each
18x²=2*3*3*x*x
6x=2*3*x
gcf=2*3*x=6x
so
18x²+6x=6x(3x)+6x(1)=6x(3x+1)
Answer:
Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
If the three are to be next to each other,
First, we arrange the three
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
So, the total arrangement, when they have to be next to one another is:
The probability is:

Express as percentage
Answer:
-85m, -2.4m, 0m, 88m, and 1,011m
Step-by-step explanation:
<span>3(5x + 4) - 20 - 13x = -4
first use the distributive property with </span><span>3(5x + 4)
15x+12-20-13x=-4
combine like terms
2x-8=-4
add 8 to both sides
2x=4
divide both sides by 2
x=2</span>
Original position was let's say 40 yard line.
You must get to the 50 yard line for a first down.
Losing 26 1/3 yardage, you are at the 13 2/3 location
You would need (36 1/3) to get to the 50 yard line.
