6.4 cm is the needed circumference of the gasket following dilatation with a scale factor of 2.
<h3>
What does circumference mean?</h3>
The boundary length of any circular shape is known as the circumference.
<h3>What is scale factor?</h3>
A scale factor is a quantity multiplier (also known as a scale). The scaling factor for x, for instance, is represented by the letter "C" in the equation y = Cx. The factor would be 5 if y = 5x were the equation.
<h3>
According to the given data:</h3>
After scale factor 2 is applied, 6.4 cm must be the gasket's needed circumference.
It includes a rubber gasket with a 3.2 cm circumference. The circumference of the gasket has must be calculated after scaling up by factor 2.
Here,
3.2 cm is the gasket's circumference.
The circumference changed upon scale factor 2 dilatation.
Dilated gasket circumference: 2 * 3.2 = 6.4 cm
As a result, 6.4 cm is the needed circumference of the gasket following dilatation with a scale factor of 2.

The answer is 36
if you substitute the numbers in, the equation would be..
-3(2-4)^2 so
2-4 is -2
-3 x -2 = 6
and 6^ is the same thing as 6 x 6
so 6^2= 36
Answer:
B. /AB/ = units
Step-by-step explanation:
A quadrilateral is the class of four sided figures. Examples include: squares, rectangles, rhombus, kite, parallelogram, trapezium etc.
From the graph, the quadrilateral is in the form of a trapezium.
the length of the side AB can be determined by:
Draw a perpendicular from B to meet AD at E to form triangle ABE,
From triangle ABE, AE = 3 units and BE = 6 units. Applying the Pythagoras theorem to determine the length AB, we have;
= +
= +
= 36 + 9
= 45
Find the square root of both sides,
/AB/ =
Thus,
/AB/ = units
