Answer:
28%
Step-by-step explanation:
3600$ × 20%
=3600 ×(20/100)
=3600 × 0.2
= 720
Actual Price = 3600 - 720
= 2880
Profit is at 4000$ = 4000 - 2880
= 1120$
%profit = (1120/4000) × 100
profit = 28%
Answer:
(x+c)(x-d)
Step-by-step explanation:
if x²-ax-b=(x-c)(x+d)
from vieta theorem
c + d = -(-a)=a
cd = b
if x²+ax-b
from vieta theorem
c + d = -(a)=-a
cd = b
so the same c d but in opposite sign (x+c)(x-d)
It would be 0.
5 times zero is zero, adding 6 will make it equal to 6.
