Answer:
We have been given an equation 
We will factorize it by middle term splitting.
Step 1: 
Taking common factors out by clubing first two terms ad last two terms
Step 2: 
Step 3: 
Equating both above factors to zero as:
Step 4: 
And 
.
Answer:
1
pages
Step-by-step explanation:
Since the concert promoter started with 2 
pages of ads but had to cancel 1 
, subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:
2 = 2 
- <u>1 </u> - <u>1 </u>
1 pages
In order to subtract fractions, you need to have like denominators, so you need to convert into an equivalent fraction with a denominator of '8'. Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
Your answer would be C. 27/190.
This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.
The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.
The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.
I hope this helps!
The fraction in its simplest form is 27/100 .
