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

Write an equation to find the amount of interest $450,000 earns in 1 year at a simple interest rate of 3.5%.
telo118 [61]

Answer:

The required equation for the amount of Simple Internet = \frac{450,000 \times 1 \times 3.5}{100}

Step-by-step explanation:

Here , Principal amount = $450,000

Time  = 1 year

Rate of Interest = 3.5%

Now,SIMPLE INTEREST  = \frac{P \times R \times T}{100}

So, here SI  = \frac{450,000 \times 1 \times 3.5}{100}

Hence, the required equation for the amount of Simple Internet = \frac{450,000 \times 1 \times 3.5}{100}
