Answer:
20 in
Step-by-step explanation:
Vol. = Bh where B is the area of the base and h is the height of the prism
500 = 25h
h = 20 in
2x^2+9x-6 i found this by subtracting 3x^2+7x from the other equation
1st ring=$50
2nd ring=$37.50
3rd ring=$25
$50+$37.50+$25 =$112.50 total cost before tax
$112.50 X 1.08=$121.5 total cost and tax
3 X $50 X 1.08=$162 total cost without discount deal
$162 - $121.50 =$40.50 savings
C is the correct answer because in a title, you always want to capitalize the bigger and more describing words.
Hope this helped!
