She will jog 1 mile in 2/10 hour. Therefore in 1 hour she will jog 5 miles.
Lilli's rate is 5 miles per hour.
The right answer is the 2nd one.
It's using the quadratic equation
Answer:
(x-2)(x-6)
Step-by-step explanation:
We look for two integers which multiply to +12 but add to -8 and we find those numbers by looking at the factors of 12={1,2,3,4,6,12}
We find that by picking 6 and 2,6×2=12 but 6+2 is not -8 so we tweak that as -6 and-2
By so doing, now -6×-2=12,-6+(-2)=-8
so we factor to get (x-2)(x-6)
To find that, just multiply 5x3 and your answer will be 15 :))
