I rlly need help with these 3 problems asap. tysm to who ever will help me 
1: A dilation with scale factor -3 maps X to \(X'\) and Y to \(Y'\) Given \(X'Y'=2,\) find XY
2: In triangle ABC, AB = BC, and CA=6
- Triangle ABC is first rotated clockwise about A for \(90^\circ\) to triangle \(AB_1C_1\)
- Triangle \(AB_1C_1\) is then reflected over \(\overline{B_1C_1}\) to triangle \(A_1B_1C_1\)
- Triangle \(A_1B_1C_1\) is then translated 8 units to the right to triangle \(A_2B_2C_2\)
- Triangle \(A_2B_2C_2\) is then dilated about A to triangle \(A_3B_3C_3\) with scale factor -4
What is the perimeter of triangle \(A_3B_3C_3 ?\)
3: A reflection maps A to B and C to C If AB = 12 then what is the shortest possible length of
\(\overline{AC}?\)
