1. We cannot pick both of the positive numbers 4 and 5 because the third one would be negative, and the overall product negative.
2. So we pick 5, the largest of (4, 5) and 2 negative numbers
3. Since the multiplication of the 2 negative numbers is positive, we pick the ones with larger absolute value, so -3 and -2
Answer: 5*(-3)*(-2)=5*6=30
Answer:
x=3
Step-by-step explanation:
cross multiply
5(x+3)=3(x+7)
5x+15=3x+21
5x+15-3x=3x+21-3x
2x+15=21
2x+15-15=21-15
2x=6
x=3
