Step-by-step explanation:
C??
I think
The solutions would be +0.37 and -0.37.
When completing the square, we take 1/2 of the value of b (in this case 5). 5/2=2.5. We then square this number: 2.5²=6.25. We add this value to both sides of the equation:
x²+5x+6.25 = 2+6.25
(x+2.5)² = 8.25
Take the square root of both sides:
√(x+2.5)² = √8.25
x + 2.5 = 2.87
Subtract 2.5 from both sides:"
x+2.5-2.5 = 2.87-2.5
x = 0.37
We have to take the positive and negative values for solutions, however, since a square root has both positive and negative answers.
Answer:
it would be 5

Answer:
360
Step-by-step explanation:
Number of customers who make purchases with a credit card
=15 out of every 25= 
The fraction 3/5 represents the part of the customer that makes purchases with credit cards.
Therefore if there are 600 customers tomorrow, 3/5 of them will use a credit card.
360 credit card can be expected.
18 . it's increasing by 5 every time so the next one after 23 is 28
