Answer:
2(x² - 2)(x² - 8)
Step-by-step explanation:
Given
2 - 20x² + 32 ← factor out 2 from each term
= 2( - 10x² + 32)
let u = x², then
- 10x² + 32 = u² - 10u + 32 = (u - 2)(u - 8)
change u back to x²
- 10x² + 32 = (x² - 2)(x² - 8) and
2 - 20x² + 32 = 2(x² - 2)(x² - 8) ← in factored form
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The volume of a rectangular pyramid is equal to
where
L is the length of the rectangular base
W is the width of the rectangular base
H is the height of the pyramid
If the pyramid is scaled proportionally by a factor of k
then
the new dimensions are
L=kL
W=kW
H=kH
substitute and find the new Volume V'
The new volume is equal to the scale factor k elevated to the cube multiplied by the original volume
