112.5 seconds per lap. As you need to convert the minutes to seconds, 7 x 60 = 420 + 30 = 450
450/4 = 112.5
Answer:
9
Step-by-step explanation:
20-11=9
Complex roots occur as conjugates so the other root is 3 + 2i
so we have the factored form
(x - (3 - 2i)(x - (3 + 2i)
= (x - 3 + 2i)(x - 3 - 2i)
= x^2 -3x - 2ix - 3x + 9 + 6i + 2ix - 6i- 4i^2
= x^2 -6x + 9 + 4
= x^2 - 6x + 13 Answer
