Answer:  11 down and 9 right
<u>Step-by-step explanation:</u>
Slope IS rise over run where the top number of the fraction (numerator) determines the vertical distance --> positive is up, negative is down
and the bottom number of the fraction (denominator) determines the horizontal distance --> positive is right, negative is left.
Given slope = -11/9
the numerator is -11 so the "rise" is  DOWN 11 units
the denominator is 9 so the "run" is RIGHT 9 units

The isosceles triangle is missing so i have attached it. 
Answer:
Length of unknown side = 5p + 6
Step-by-step explanation:
In isosceles triangle, two of the sides are equal. In the attached triangle, we see that one of the equal sides is given as 5p + 3.
Thus,the second equal side is also 5p + 3.
Now, perimeter of a triangle is the sum of the three sides.
We have two sides and let the third side be denoted as x. 
Thus;
Perimeter = (5p + 3) + (5p + 3) + x
We are given perimeter = 15p + 12
Thus;
(5p + 3) + (5p + 3) + x = 15p + 12
10p + 6 + x = 15p + 12
Rearranging, we have;
x = 15p - 10p + 12 - 6
x = 5p + 6
 
        
             
        
        
        
Answer:
Difference between the original and current volumes = 4013140.30 cubic feet
Step-by-step explanation:
Largest pyramid has the square base with one edge = 754 feet
Area of the square base = (Side)²
                             = (754)²
                             = 568516 square feet
Volume of the pyramid = 
                                        = 
                                        = 91152065.3 cubic feet
After erosion, 
Area of the base = (745)² = 555025 square feet
Volume of the pyramid = 
                                        = 87138925 cubic feet
Difference between the original and current volumes of the pyramid
= 91152065.30 - 87138925 
= 4013140.30 cubic feet
