Answer:
x³ - 8x² - 11x + 148
Step-by-step explanation:
Given that x = 6 + i is a root then x = 6 - i is also a root
Complex roots occur as conjugate pairs.
The factors are therefore (x - (6 + i)) and(x - (6 - i))
Given x = - 4 is a root then (x + 4) is a factor
The polynomial is the product of the factors, that is
p(x) = (x + 4)(x - (6 + i))(x - (6 - i))
= (x + 4)(x - 6 - i)(x - 6 + i)
= (x + 4)((x - 6)² - i²)
= (x + 4)(x² - 12x + 36 + 1)
= (x + 4)(x² - 12x + 37) ← distribute
= x³ + 4x² - 12x² - 48x + 37x + 148
= x³ - 8x² - 11x + 148

Answer:
66
Step-by-step explanation:
105+420=525 (Total Money)
7x3.25=22.75 (Cost of all bracelets)
8x11.74=93.92 (Cost of all necklaces)
93.92+22.75=116.67 (Cost of all Christmas presents)
525-116.67=408.33 (Total money - Cost of all Christmas presents)
408.33/6.15=66.39... (Amount of necklaces)
since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!
