Answer:
2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
= 4.22×3×3.15576/1.609344×10^(8+7-3) mi
≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
The answer is no real solution
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2=−12x−15
Step 1: Subtract -12x-15 from both sides.
3x2−(−12x−15)=−12x−15−(−12x−15)
3x2+12x+15=0
Step 2: Use quadratic formula with a=3, b=12, c=15.
x=
−b±√b2−4ac
2a
x=
−(12)±√(12)2−4(3)(15)
2(3)
x=
−12±√−36
