Answer:
38 divided by 16146.2 = 0.0023534949 then rounded to the nearest hundredth = 0.00
38. divided by 16146.2= The same as that one ^
1614.62 divided by 3.8= 424.9 then rounded you get 424.90
Answer:
45 because 7 x 9 = 63 so you have to do 5 x 9 = 45

Answer:
5n/2 - b =a
Step-by-step explanation:
5n/2 = (a + b)
subtract b from both sides
5n/2 - b = a
Answer: B) 0 real roots
---------------------------------------
The general rule is...
if D > 0, then you have two different real roots (see note below)
If D = 0, then you have exactly one real root
If D < 0, then you have no real roots (the two roots are imaginary/complex)
where D is the discriminant found by the formula
D = b^2 - 4ac
Note: If D is also a perfect square, then the two real roots are also rational. This assuming that a,b,c are rational.
