Answer:
x = ± 8i/11
Step-by-step explanation:
121x2+64=0
121x^2 = -64
x^2 = -64/121
x = +/- √(-64/121)
x = +/- 8i/11
You would divide 28/3 because that's how many miles it would take. 28/3=9 1/3. Also, to help understand better, 3 miles is equal to 1 hour. So the equation would look like this: 3/1=28/?. To solve it like this, you'd divide 28/3 or 3*?=28. Whatever the answer is(9.33)you do it to the bottom. So 1*9.33. that equal 9 hours 20 min
88 is your answer 100% sure.
