Answer:
1:12 One sketch every 12 minutes. Four Easy Steps Below!
Step-by-step explanation:
The ratio will be sketches:minutes
*We try to find how many minutes it takes him to make 1 sketch, since it's asking for lowest terms!
- find the larger ratio= 5:60 *60 minutes in an hour, we're finding minutes! Convert one hour to minutes*
- 5:60.... Divide 60 by 5. *You're finding the time it takes for one sketch*
- 12
- 1:12 1 sketch every 12 minutes. This is the lowest term.
What is the difference between multicellular and unicellular?
Add 10 on both sides
6x^2+12x+12=0.
Divide by 6 on both sides.
X^2+2x+2=0
Plug into quadratic formula
X=(-2 +\- (2^2-4•1•2))^1/2) /2•1
X=(-2 +\- (-4)^1/2)/2
X=(-2+\- 2i) /2
X=-1+\- I
X= -1 + i OR -1 - i
