Answer:
The time may be calculated by making the equations equal each other:
2w +7 = .5w + 10
1.5w = 3
weeks = 2
Step-by-step explanation:
A(n) = -14+(n-1)(2)
A(14) = -14+(14-1)(2)
A(14) = -14+26
A(14) = 12
Answer: The answer is 1320 hope this is right.
Scalene and obtuse
obtuse cuz 132 is greater than 90
scalene cuz all three sides have different lengths
