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)
Answer:
X=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6−4x=6x−8x+2
6+−4x=6x+−8x+2
−4x+6=(6x+−8x)+(2)(Combine Like Terms)
−4x+6=−2x+2
−4x+6=−2x+2
Step 2: Add 2x to both sides.
−4x+6+2x=−2x+2+2x
−2x+6=2
Step 3: Subtract 6 from both sides.
−2x+6−6=2−6
−2x=−4
Step 4: Divide both sides by -2.
−2x/−2=−4/−2
Step 5 :Answer

Step-by-step explanation:
x=55. Explanation: If x varies inversely as y , then that means: y=kx. Let's multiply both sides of the equation by x to find k . k=xy.
ANSWER:
314 yd^2
Explanation:
Use the formula for the area of the circle. Since the diameter is 20, the radius is 20/2=10
Split the composite figure in two
a rectangular prism and a isosceles triangular prism
when u have the figures separated use the formulas for the each
