Answer:
The answer is below
Step-by-step explanation:
The standard form of the equation of an ellipse with major axis on the y axis is given as:

Where (h, k) is the center of the ellipse, (h, k ± a) is the major axis, (h ± b, k) is the minor axis, (h, k ± c) is the foci and c² = a² - b²
Since the minor axis is at (37,0) and (-37,0), hence k = 0, h = 0 and b = 37
Also, the foci is at (0,5) and (0, -5), therefore c = 5
Using c² = a² - b²:
5² = a² - 37²
a² = 37² + 5² = 1369 + 25
a² = 1394
Therefore the equation of the ellipse is:

Answer:
$(25+5x) or $5(5+x)
Step-by-step explanation:
multiply x with $5 = $5x
add $25 to $5x = $(25+5x)
Answer:
$6.25 for each CD
Step-by-step explanation:
6.25 x 400 = 2,500
2,500 - 2,000 = 500
there is a 500 profit
Add 110 to both sides so you get -240
then divide it by 16 so you get x = -15
Check
-350 = -110+16(-15)
-350 = -110 - 240
-350 = -350

I just finished learning this in my school xD</span>
You are combining like terms. It will be 5a+9+b²
