Answer:
<h3>-x+3</h3>
Step-by-step explanation:
Given the expression
-x^2 + x + 3 x - 3
Factorize
(-x^2 + x) + (3 x - 3)
-x(x-1)+3(x-1)
= (x-1)(-x+3)
Hence one of the quotient is -x+3
The answer is 7 because the first part of the ratio says amount of states that border an ocean.
The both started at 11.00 a.m then they will meet at 11:15 a.m
We have given that
Two turtles, which are 750 meters apart and the are moving towards each other
average speed of 1 km/h, and the other travels 1 km/h faster
Therefore we have to find When will the turtles meet.
First turtle travels at an average speed of 1 km/h.
Thus; v₁ = 1 km/h
Second turtle travels at an average speed of 1 km/hr faster than the first.
Thus; v₂ = 2 km/h
Since second turtle is moving 2 times faster than the first one, it means the second turtle will cover 2/3 of the total distance while the first will cover 1/3 of the total distance at the point they will meet.
What is the value of 1 kilometre in meter
1 km=1000 meter
So,
Distance covered by turtle 2




Since they both started at 11.00 a.m then they will meet at 11:15 a.m
