The answer would be A: -2.5, 0
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
Answer:
C is the answer
Step-by-step explanation:
24 + x ≥ 55
x ≥ 31
solutions are all values to the right of 31, including 31
x=2y is linear and can also be writtend as y=x/2
Answer:
m=5
Step-by-step explanation:
5m-3=22
- take 3 the other side by doing the opposite operation
5m= 22+3
5m= 25
- then divide it by 5 on both sides to get the value of m.
- 5m÷5=25÷5
- 5and 5 cancels out and the answer becomes :
m=5
