Answer:
x = ± sqrt(-49)
or x = ± 7i
Step-by-step explanation:
x^2 +49 = 0
Subtract 49 from each side
x^2 +49 -49 = 0-49
x^2 = -49
Take the square root of each side
sqrt(x^2) = ± sqrt(-49)
x = ± sqrt(-49)
We have to complex numbers to solve
x = ± sqrt(-1) sqrt(49)
sqrt(-1) = i
x = ±i *7
x = ± 7i
If 3 pounds cost $8.31, then the product is being sold as 1 for $2.77.
If 5 pounds cost $12.59, then the product is being sold as 1 for $2.51.
It is better to buy 5 pounds for $12.59 because you are getting more for your money.
The volume is 27 cubic centimeters.
