1st : x² -8x - 24 =0
x'= ( 8 + √[(8² - 4 (1)(-24)] / 2 and x" = ( 8 - √[(8² - 4 (1)(-24)] / 2
x' = (8+√160) / 2 = (8+√(16x10) / 2 and x = (8+4√10)/2, simplify by 2
x' = 4+2√10, same for x" = 4 -2√10
2nd: Let x be the number of people to invite.
Given: cost of the band $750
cost of food : x.$2.25
Total cost = $750 + $2.25.x
To find the average you divide the total cost by the number of guest, that is x.
Average = ($750 + $2.25.x)/x
a)- For an average of $2.75
($750 + $2.25.x)/x =2.75 Solve for x and you will find 1500 guests
b)- For an average of $3.25
($750 + $2.25.x)/x =3.25 Solve for x and you will find 750 guests
So:
750<p<1500 (answer number 4)

Answer:You will see that, in the tradition of a griot speaking truth to power, Ms. Gorman often turns to her literary mantra, “I am the daughter of Black writers, who are descended from Freedom Fighters, who broke the chains who changed the world. They call me.”
