Step-by-step explanation:
1. We we can split 4p into 9p - 5p, and now we have 3p² + 9p - 5p - 15 = 0. We can take out 3p from the first 2 terms and -5 from the last 2 terms. This gets us 3p (p + 3) -5 (p + 3) = 0. These two terms have (p + 3) as a common facor, so we can take that out as well, which give us (p + 3)(3p - 5) = ). Using Zero Product Property, p + 3 = 0 and 3p - 5 = 0, and when we solve each equation, we get p = -3, p= 5/3.
2. We will use the same process.
6x² + 14x - 3x - 7 = 0
2x (3x+7) - 1 (3x+7) = 0
(3x + 7)(2x - 1) = 0
3x + 7 = 0, 2x - 1 = 0
x = -7/3, x=1/2
Hope this helps!
Perimeter of a square = 4s = 20ft
s = 20/4 = 5 feet
New length = 5 + 2 = 7 ft
New width = 5 - 1 = 4ft
New perimeter = 2(7 + 4) = 2(11) = 22ft
Answer:
Step-by-step explanation:
- Deposit = P 10000
- Interest rate = 6% simple per year
- Time = 4 years
<u>Total in 4 years:</u>
- 10000*(1 + 4*6/100) =
- 10000*1.24 =
- 12400
After 4 years the amount is P 12400
Answer:
3/10
Step-by-step explanation:
There are 10 students
5 of them voted either Los Angeles or New York
That means ignore (screw) the other 5 people
If 2/10 students chose Los Angeles,
that is 2/5 because the others didn't choose those cities that are part of the equation (nobody asked about the other people)
So if 5 people chose two groups of cities, and two people chose one city, that meant 3 chose the other
3/10 (remember its out of all of them) Students Voted for New York
Hope this helps :)
