Let x be the time in hours it takes to go 80 miles. Set v(t) = 80.
∫v(t)dt = 80 from 0 to x
Then 80x - 80(0) = 80
80x = 80
x = 1 hour
Answer:
x = -23

Step-by-step explanation:
i got it right
The perimeter of a triangle is:
P = a + b + c
We are given that:
b = a + 3
c = 2 a – 3
Therefore:
68 = a + a + 3 + 2 a – 3
68 = 4 a
a = 17
and,
b = a + 3 = 20
<span>c = 2a – 3 = 31</span>
