Answer:
x = -3±sqrt( 5)
Step-by-step explanation:
(x + 3)^2-5=0
Add 5 to each side
(x + 3)^2-5+5=0+5
(x + 3)^2 = 5
Take the square root of each side
sqrt((x + 3)^2 )=±sqrt( 5)
x+3 = ±sqrt( 5)
Subtract 3 from each side
x+3-3 = -3±sqrt( 5)
x = -3±sqrt( 5)
42 (1- 25/100) = 63/2 = 31.5 dollars
answer is $31.50

0.6 would be the same as $0.60 AKA 60 cents and 0.06 would be the same as 6 cents
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
