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

Step-by-step explanation:
Answer:
odd function
Explanation:
To determine if a function f(x) is even/odd consider the following.
• If f(x) = f( -x) , then f(x) is even
Even functions are symmetrical about the y-axis.
• If - f(x) = f(-x) , then f(x) is odd
Odd functions have symmetry about the origin.
Test for even function
f(−x)=4(−x)3=−4x3≠f(x)
Since f(x) ≠ f( -x) , then f(x) is not even
Test for odd function
−f(x)=−(4x3)=−4x3=f(−x)
Since - f(x) = f( -x) , then f(x) is odd

Answer:
Point C
Step-by-step explanation:
We want to reflect across the x axis
That means the y coordinate changes sign
Z = ( 5 1/2 , 3)
Z' = ( 5 1/2 , -3)
That is point C
12/10, 1.2, and any of the infinite multiples of the fraction such as 24/20, 120/100 etc...
