Answer:
6x^2 + 2x - 5 (Option C)
Step-by-step explanation:
1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.
2. Second, add -5x and 7x (which is 2x)
3. Lastly, subtract 3 and 8, which is -5
WHY DOES THE ANSWER HAVE A NEGATIVE 5?
The equation looks like this: +3 + -8
You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)
Old coordinate
As center of dilation is origin the scale factor only multiplied with B
So
new coordinate
B'
- 1/2(2,-6)
- (2/2,-6/2)
- (1,-3)

Explanation:
1 yard = 3 feet
We'll divide by 3 to convert from feet to yards
- 27 feet = 27/3 = 9 yards
- 18 feet = 18/3 = 6 yards
The basement is 9*6 = 54 square yards in floor area.
At $32 per square yard, the total cost to carpet the floor is 32*54 = 1728 dollars.
