Step-by-step explanation:
Answer: 
Step-by-step explanation:
You need to use the SAS area formula. This is:
Given the triangle ABC, you know that:
Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:
H(x) = 4x² - 8x - 60
0 = 4x² - 8x - 60
0 = 4(x²) - 4(2x) - 4(15)
0 = 4(x² - 2x - 15)
4 4
0 = x² - 2x - 15
0 = x² - 5x + 3x - 15
0 = x(x) - x(5) + 3(x) - 3(5)
0 = x(x - 5) + 3(x - 5)
0 = (x + 3)(x - 5)
0 = x + 3 or 0 = x - 5
- 3 - 3 + 5 + 5
3 = x or 5 = x
5 hours + 4 hours = 9 hours
30 minutes + 45 minutes =75 minutes
60 minutes in an hour, so 75 minutes =1 hour and 15 minutes, or 1.25 hours
9 hours + 1.25 hours =10.25 hours or 10 hours and 15 minutes.
1. an = 15 (1/3)^(n-1)
because it starts from 1,2,3,4........ for n.
2. a₁= 10(-8)^(1-1)=10
an= 10(-8)^(n-1)
3. an=2(1/3)^(n-1)
4. a₁= 1/2 (4/3)^0=1/2
an= 1/2 (4/3)^(n-1)
Hopes this loves.
