Answer:
L' = (-36, 0)
Step-by-step explanation:
If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)
∵ A dilation has a center (0, 0)
∵ The point L is (-4, 0)
∴ x = -4 and y = 0
∵ The scale factor of dilation is 9
∴ k = 9
→ By using the rule above
∵ kx = 9(-4) = -36
∵ ky = 9(0) = 0
∵ The image of the point L is (kx, ky)
∴ L' = (kx, ky)
∴ L' = (-36, 0)

The value of x from the figure is 70°
<h3>How to determine the value</h3>
It is important to note that alternate angles are equal and angles in a triangle sum up to 180°
We then have that,
x + 50 + 60 = 180 °
x + 110 = 180°
Make 'x' subject
x = 180 - 110
x = 70 °
Thus, the value of x from the figure is 70°

Answer:
B
Step-by-step explanation:
Here, we are told that the rectangle is enlarged by a factor of 6, we now want to calculate the new area of the said rectangle.
Now, for the rectangle to have an area of 20, mathematically the area of a triangle can be calculated using the formula L * B
where L is the length and B is the breadth
our product here is 20, so any product that gives 20 would be a good fit as the value of the width and length of the rectangle
So, let’s say the sides measure 5 inches by 4 inches
Enlarging these by a factor of 6, we have 30 inches by 24 inches
The new area of the rectangle would thus be ;
30 inches * 24 inches = 720 inches^2
