Answer:

Step-by-step explanation:
We need to find the value of x so that the value of given function becomes 21 .
We have ,

Now , for finding x ,
Answer:
12 units
Step-by-step explanation:
Notice that as we go from Q to R, x (the horizontal distance) increases by 12 and y (the vertical distance) does not change. Thus, the distance between the two points is merely the horizontal distance, 12 units.

Answer:
The volume of pyramid B is 3.5 times greater than the volume of pyramid A
Step-by-step explanation:
The area of squared based a pyramid is given by:

Where 's' the length of the side of the base and 'h' is the height.
For pyramid A:
h= 100 m
s= 356/4 = 89 m

For pyramid B:
h= 215 m
s= 456/4 = 114 m

Pyramid B has a greater volume and the ratio between volumes is:
