Since both rectangles are similar, the following ratio must be fulfilled:

By multiplying both sides by 14, we get

and by subtracting 9 to both sides, we have

Therefore, the answer is 12.
Answer:
36 and 54
Step-by-step explanation:
54-36=18
54+36= 90

Subtract 3/100 to both sides:

Cross multiply:

Divide 100 to both sides:

Or we could just multiply both sides of the equation by 100, to give us:

Subtract 3 to both sides:
301 , 117
=117 : 301
because they are telling to tell ratio of boys to the ratio of total seniors
Answer:
The correct option is D) (5x − 2)(2x − 3).
Step-by-step explanation:
Consider the provided expression.

Where x is time in minutes.
We need to find the appropriate form of the expression that would reveal the time in minutes when the trough is empty.
When the trough is empty the whole expression becomes equal to 0.
Substitute the whole expression equal to 0 and solve for x that will gives us the required expression.




Now consider the provided option.
By comparison the required expression is D) (5x − 2)(2x − 3).
Hence, the correct option is D) (5x − 2)(2x − 3).
