X^2+14x-176=0
(x+22)(x-8)
x=-22,8
This is because the 2 numbers in the factorisation must have multiple of 176& and a sum of 14
Answer:

Step-by-step explanation:

Add 7 to both sides:
Multiply both sides by -1:
Divide both sides by 5:

Part 1) Smooth curve going up the Origin, means, the distance of the bus is increasing with increase in time. In other words, Bus is in the motion.
Part 2) Distance is constant here & Bus is not moving at all.
Part 3) Distance is decreasing, means bus in moving in opposite direction, and it is said to be the negative displacement.
Part 4) Again, The Distance is constant here & Bus is not moving at all.
Part 5) Here, Displacement is negative, which means bus is moving in the opposite direction and reached the starting point.
Part B) It is Increasing at: Part 1
It is decreasing at: Part 3 & 5
It is constant at: Part 2 & 4
C.) Graph is non-linear, as it shows deviation through the complete journey of the Bus.
Hope this helps!
