48x0.2= $9.6
$48-9.6=$38.40 Her friend is incorrect.
40/48 =0.83 or about 83% So, in this case she only got 17% off. :)

Answer:
A. x > 13
Step-by-step explanation:
x-3>10
x>10+3
x>13
Answer is 13 because the numbers are increasing though odd numbers that are also increasing if that makes sense.
It’s going from 4 > 9 > 16 > 25 > 36
so from 4-9 it adds 5 and from 9-16 it adds 7 and goes on so that’s it’s like
+5 > +7 > +9 > +11
sorry if it doesn’t make good sense
Answer:
33/10
Step-by-step explanation:
I used a calculator sorry if I am wrong
Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
