Answer:
Explanation:
25) We know that sides AC and VX correspond, so the scale factor is AC/VX = 34/51 = 2/3.
26) The ratio of the areas is the scale factor squared, so (2/3)^2 = 4/9.
27) Conjecture is probably the reasoning I provided for question 26. To justify, I assume they want you to prove it, so just consider a triangle with base b and height h. Then, consider a scale factor of k to make a new triangle with base kb and height kh. The area of the preimage is 1/2 bh but the area of the image is 1/2 kb kh, and since the ratio is just k^2, the conjecture is true.
