Answer:
-6/13
Step-by-step explanation:
The graph that is proportional is B because it goes through the origin and the ratio remains the same.
Answer:125=n
Step-by-step explanation: 375 divided by 3 is 125
Lets say that the two unknown integers are

and

.
We know the following things about

and

:


And, we want to find

.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:

So, given what we know about the unknown integers, the previous can be written as:

We can easily solve for

:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of

and

, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
