Answer: 2(4p - 25q)
Explanation: 4p*2 = 8p - 25q*2 = 8p - 50q = 2(4p - 25q)
Answer:
3x^2 - 3x + 18
Step-by-step explanation:
x*3x=3x^2
(x*6)+(-3*3x)=-3x
-3*6=-18
If it is, then you can solve the equation by taking the square root of both sides of the equation. ... Next, if the coefficient of the squared term is 1 and the coefficient of the linear (middle) term is even, completing the square is a good method to use. Finally, the quadratic formula will work on any quadratic equation
Answer:
2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
m = ( 8-2)/(3-0)
= 6/3
= 2
Answer:

0.11 seconds

Step-by-step explanation:
= Time taken by the pebble to hit the water
= Time taken by the sound to travel to the observer
= Time taken by the observer to listen to the splash after stone is thrown = 3 s

a = g = Acceleration due to gravity = 
= Speed of sound = 340 m/s
The distance traveled by the pebble

Distance traveled by the sound

The distance traveled by the sound and the pebble is equal

Since
the value of
cannot be greater than 3.
So, time taken by the sound to reach the observer is 0.11 seconds.
Time taken by the pebble to hit the water is 
Depth of the well is
