Answer:
-191
Step-by-step explanation:
Replace variables with corresponding value.
3(3) + (-5)^2 - ((3)(-5))^2
Solve exponent.
3(3) + 25 - 225
Multiply.
9 + 25 - 225
Combine like terms.

<u><em>-1,2</em></u> is the correct answer
The best information that describes your routes is the second route was steeper than your first, and the second route was higher up the mountain.
<h3>What is the slope of a linear equation?</h3>
The slope of a linear equation is the change in the rise over the run. So, the slope of a linear equation shows that the larger the slope, the steeper the line becomes.
From the given information:
y = 2x + 4 --- (1)
y = 4x + 1 --- (2)
Using the slope-intercept formula:
y = mx + b
From the first equation, the slope is 2 and in the second equation, the slope is 4.
Therefore, we can conclude that the second route was steeper than your first, and the second route was higher up the mountain.

To answer this question, you need to understand how to change the description into an equation. Let say that Herbert's container volume is H and Betty's container is B. Then, from the problem you can get this equation:
1. B= 200 (Betty's container hold 200 milli liters)
2. H= 7/8 B (Herbert's container hold 7/8 as much juice)
If you put the 1st equation into the 2nd, you will get:
H=7/8 (200)= 175
Then the two containers will hold
H+B= 200 + 175= 375milli liters
