Answer:
The number of units in the length of the shortest side of the triangle is 6.325 units or 2 sqrt 10.
An= -16 + (n-1)7
an= -16 + 7n - 7
an=7n -23
When the rate of change is 7
{a1 = 16, a2=-9, so the rate of rate of change is 7}
Answer: 3 buses, 2 vans
Explanation: let x be number of buses, y be number of vans,
136= 40x+8y
5=x+y
Use simultaneous equation,
136-8(5)= 40x +8y - 8(x+y)
96= 32x
x = 3
When x=3, y= 2
