I did this problem for homework. The picture below has both answers.
X=-4 x=0 x=5
5-4-12=-4-7 5+0-12=0-7 5+5-12=5-7
-11=-11 -7=-7 -2=-2
l+w=20000
l=w+4000
w+4000+w=20000
2w+4000=20000
2w=16000
w=8000
l = 8000 +4000 = 12000
William scored 8000, Luca scored 12000
<em>Answer</em>
3
<em>Explanation</em>
Let's start by factoring the expression; 3x + 24.
3 is common in both term. So, factor it out.
3x + 24 = 3(x + 8)
The number that would fill in the blank to complete the factorization of 3x+24 is 3.
