Answer:
x=1+2i/2
Step-by-step explanation:
Using the method of completing the square
(2x)²-2(2x)1 +(1)²+4=0
(2x-1)²=-4
taking square root on both sides
2x-1=2i
2x=1+2i
x=1+2i/2
Answer:
14 dimes, 21 quarters

1 dime = $0.10 and 1 quarter = $0.25. So, a value of $5.60 means
So, the system of equations is:
Make d the subject in
Substitute 35 - q for d in
Open bracket
