Solution:
Given the triangle ABC as shown below:
To draw the image,
step 1: Determine the coordinates of the vertices of the triangle.
In the above graph,
step 2: Evaluate the new coordinates A'B'C' of the triangle after a dilation centered at the origin with a scale factor of 2.
After a dilation centered at the origin with a scale factor of 2, the iniatial coordinates of the vertices of the triangle are multiplid by 2.
Thus,
step 3: Draw the triangle A'B'C'.
The image of the triangle A'B'C' is as shown below:
Answer:
Step-by-step explanation:
First cross multiply:
2(x+2)=2x-2
Then Simplify:
2x+4=2x-2
Finally, Solve:
2x-2x=4+2
Ans: No Solution
Check the picture below.
since the pyramid has 4 triangular faces and a square base, let's add their areas together and that'd be the area of the pyramid.
