The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore, to solve this problem you have to follow the proccedure shown below.
1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:
15x</span>²-3x+25x-5
2. Then, you have:
15x²+22x-5
3. As you can see, the correct answer is the last option: 15x²+22x-5
43) 50% of the time, Store A has 550 or more customers per day.
44) Distribution A appears to be skewed to the left with no outliers and a center at 500 customers. Distribution B appears to be Normal with no outliers and a center at 400 customers.
45) Store A has more customers.
