Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be
cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
The greatest common factor in this expression is 3x^4. Let's take it out:
3x^4(u^4 - 1)
u^4 - 1 is a difference of two squares and can be factored further:
3x^4(u^2 + 1)(u^2 - 1)
u^2 - 1 is also a difference of two squares:
3x^4(u^2 + 1)(u + 1)(u - 1)
