Assume that the other number is y.
we know that the addition of both number is -9
this means that:
x+y=-9
reorder this equation to seperate the y variable:
y=-9-x
Answer:
3(x-2)(x+5)
Step-by-step explanation:
1. Factor out common term 3
3(x^2 +3x-10)
2. Factor (x^2 +3x-10)
3(x-2)(x+5)
Red apples to all apples:
There are 6 red apples and 13 apples total, so the ratio it 6:13
Green Apples to All Apples:
There are 7 green apples and 13 apples total, so the ratio is 7:13.
5x+3(x-2)=90
5x+3x-6=90
8x-6=90
+6 +6
8x=96
\8 \8
X=12
