Answer:
x = 3 or x = 1
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 4 x + 3 = 0
Subtract 3 from both sides:
x^2 - 4 x = -3
Add 4 to both sides:
x^2 - 4 x + 4 = 1
Write the left hand side as a square:
(x - 2)^2 = 1
Take the square root of both sides:
x - 2 = 1 or x - 2 = -1
Add 2 to both sides:
x = 3 or x - 2 = -1
Add 2 to both sides:
Answer: x = 3 or x = 1

Answer:
Step-by-step explanation:
with the numbers that come out of result
I'd word it better next time but I got it its 2.50 an hour
60mins in 1 hour
80mi per 10min=xmi per 60min
ration and porportion
80mi/10min=xmi/60min
times both sides by 60min
480mi=xmi
answer is 480miles per hour
