The number of winners that Heather can expect is 300.
<h3>How many winners can be expected?</h3>
The first step is to determine the total number of winners to the total number of players using the information in the table.
- Total number of winners = 52 + 63 + 65 = 180
- Total number of players = 123 + 155 + 172 = 450
Ratio = 180 / 450 = 0.40
Number of winners if there are 750 players = 0.40 x 750 = 300 winners

Step-by-step explanation:
F ( x ) = x² + 2x - 24
{ factorising by middle term splitting method }
[ 24 = 2 × 2 × 2 × 3 ]
F ( x ) = x² + 6x - 4x - 24
F ( x ) = x ( x + 6 ) -4 ( x + 6 )
F ( x ) = ( x + 6 ) ( x - 4 )
Zeroes are when f(x)=0
0=x^2+9x+20
factor
0=(x+4)(x+5)
set each to zero
x+4=0
x=-4
x+5=0
x=-5
zeroes are f(-5) and f(-4)
I think it's B but if I where you I would wait until someone else comments on here to so you know for sure

answer would be
6^2
