Answer:
A) 
Step-by-step explanation:
The graph goes up 3, to the right 5 between the two points, making the slope
.
The parkers will pay A. $708.75
21 feet by 27 feet is 7 yards by 9 yards (3 feet per yard)
the area of the room is 7 yards * 9 yards = 63 square yards
if the carpet is $11.25 per square yard, multiply that number by the area
11.25 * 63 = 708.75
3x-2=4
So x equals 2
3x2-2=4
3 times 2 is six and six minus two is 4
The answer is 13(6.5+6.5)
