You would do...
4 x 2.52 = 10.08
So it would be $10.08.
You need open parentheses ,do not change signs, because it is +, and add like terms
5x²-2x+6x-4=5x²+4x-4
correct answer is B
You have two people answer and whoever answer you think is better you can mark them as brainliest
Answer:
Let the coordinate of focus be 
As per the statement: The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide.
⇒Length of Major axis=base of an auditorium = 200 feet and Length of a minor axis=wide of a auditorium = 100 ft
Semi-major axis (a) = 100 ft and
semi-minor axis(b) = 50 ft
Then, by an equation:

Solve for c:
Substitute the given values we have;

Simplify:

or
ft
Distance between the foci is, 
Therefore, the distance between the foci to the nearest 10th of a foot is, 173.2 ft
If one of them is wrong it is because it is blury! sorry!
