Answer:
324 km²
Step-by-step explanation:
The prism shown is a square pyramid
The volume of a square pyramid can be calculated by using this formula

where l = length of base, w = width of base and h = height
We are given the following dimensions...
length of base = 9 km
width of base = 9 km
height = 12 km
To find the volume of the pyramid, we plug in these given values into the formula
Hence,

V = 324
Answer:
option D
Step-by-step explanation:
Let the price be p
7% of price = 0.07p
Price after decrease = p - 0.07p
For part a x=0 because anything to the power of 0 is 1
For part b any number could be x, because 7^0 is one and 1 to the power of anything will be 1
Hope this helps!
To solve for a variable, you need to get it (x) by itself.
2x² - 4x + 5 = 6 Subtract 6 from both sides
2x² - 4x - 1 = 0 Plug this into the Quadratic Formula
a = 2 , b = -4 , c = -1
x =

Plug in your values
x =

Simplify
x =

Simplify
x =

Simplify by removing a 2 from every term
x =

Simplify by taking the fraction apart
x =

Change

to 1
x = 1

Simplify

to
x = 1
