Amount of pink dye mixed with one gallon of white paint=
Amount needed for 8 gallons = ounces
So, total dye required =
or
ounces.
Hence, option C is correct.
Answer:
2+i or 2-i (D)
Step-by-step explanation:
First you use the quadratic formula. X= (-b +/- )/2a
a=1
b=-4
c=5
X= (4 +/- )/2
X=(4 +/- )/2
The square root of -4 is 2i. i=√-1. Therefore 2i= 2√-1 .If you simplify that, it becomes √-4i.
X= (4+/- 2i)/2
X= 2+/-i
X= 2+i or 2-i
