Amelia ,Hayden and Sophie did a test the total for the test was 75 marks Amelia got 56% of 75 marks Hayden got 8/15 0f the 75 marks Sophie got 43 out of 75 marks who got the highest

Step-by-step explanation:

Amelia got 56% of 75 so

(56/100)*75=(56*75)/100=4200/100=42

Hayden got 8/15 of 75 so

(8/15)*75=(8*75)/15=600/15=40

and Sophie that got 43 out of 75

so we see that Sophie got the highest points.

Given parameters:

  Total test score = 75marks

 Percentage of Amelia score  = 56%

 Fraction  of Hayden's score =

  Sophie's score  = 43marks

Unknown:

The person with the highest score  = ?

Solution:

  Since total score = 75marks;

Amelia's score =   = 42marks

 Hayden's score =   = 40marks

 Sophie's score  = 43 marks

The person with the highest score is Sophie with a mark of 43.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
