Answer:
<h2>B. The difference in height between the pelican and the heron is 33 feet.</h2><h2>E. The difference in height between the pelican and the trout is 40 feet.</h2>Step-by-step explanation:
Notice that the heron and the pelican are above sea level, that means they are in positive territory.
On the other hand, the trout is below the sea level, so it's in negative territory.
The difference in height between the heron and the pelican is
Notice that this difference should be positive, because we just want to know the difference between heights.
On the other hand, the difference between the pelican and the trout is
Because the difference is a positive number.
Therefore, the right answers are B and E.
Keep these rules in mind:
Firstly, solve the exponent and multiplication:
Next, combine like terms:
Next, subtract 4x² on both sides:
Next, subtract 25 on both sides:
Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:
<u>Your answer is x > 2.</u>
