Answer:
Step-by-step explanation:
Given
Shape: Rectangle
Diagonals: AC and BD
Required
Determine BD
From the question, we understand that the shape is a rectangle and its diagonals are AC and BD
Every rectangle has 2 diagonals, both of which are equal.
This implies that:
Recall that:
Hence,
To find an equivalent expression, you can distribute the 4 to the parenthese. To do this, multiply the four by each term separately, then add all of the resultant terms.
4*x=4x
4*7y=28y
Therefore, the answer is 4x+28y

Answer:
6 gallons per minute
Step-by-step explanation:
Let the function that models the quantities of water, Q (in gallons) in a pool over time, t (in minutes), is
Q = a + bt ........... (1)
Now, Q(t = 0) is given to be 50 gallons.
So, a = 50 and b denotes the rate at which the quantity of water in the pool is decreasing and it is given by the slope of equation (1).
Now, two points on the graph are (0,50) and (1,44).
So, the slope = b = = - 6 gallons per minute.
Therefore, the equation of this situation is given by Q = 50 - 6t, where the slope is equal to - 6 gallons per minute. (Answer)
