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
Ans: 20.25
can convert the mixed numbers fractions to improper fractions before making the denominators the same and coming up with the answer in decimals
hope this helps:))

Answer:
Well, I kind of know this but I don't wanna be wrong so here and the sides if it helps
1. 2x8x8
2.2x8x8
3. 8x8x10x10
It's because most of them are the same measurements therefore are the same angles. 1 is just the name of the triangle and is based off their sides and measurements
