Kristen needs at least 500 points to earn the next trophy on her video game. she has 418 points. how many points must she earn to win he trophy?

Points required to win the trophy =500

Points Kristen already scored = 418

Let Kristen require x points to win the trophy.

So making an equation using the information we have,

Now we have to solve this equation to get the value of x .

subtracting 418 from 500 , we have,

x=82

So Kristen require at least 82 points to win the trophy.

11 feet 6 inches and 8 feet 6 inches

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
