Before I can answer, I need to know the shape.
Answer:
(x,y) → (ax,ay) .
Step-by-step explanation:
A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:
(x,y) → (ax,ay) .

Answer:
x = 18
Step-by-step explanation:
Given
6 - x = - 12 ( subtract 6 from both sides )
- x = - 18 ( multiply both sides by - 1 )
x = 18
Answer:
42 cm ^2
Step-by-step explanation:
The area of a triangle is 1/2 B x H ( one half base times height)
The base is 6 cm and the height is 14 cm. So the full equation now is
1/2 (6) (14)
First you multiple 6 times 14 which is 84. Next you just divide it by 2 because 1/2 is half of the number. 84 divided by 2 is 42. So your answer is
42 cm ^2 (centimetres squared)
