Need these done fast pls will give brainliest 1. A dilation from center O with scale factor r1=14 maps a point P to another point P′ . Then a second dilation from O with scale factor r2 maps P′ to P .

What is the value of r2 ?

2. Let O , P , and Q be distinct collinear points with PQ=3 . Let P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4 .

What is the length of the image segment P′Q′ ?

3. Square A′B′C′D′ is the image of square ABCD under a dilation from center O1 by scale factor r . Square A′′B′′C′′D′′ is the image of square A′B′C′D′ under a dilation from center O2 by scale factor 14 . The side lengths of square A′′B′′C′′D′′ are 18 of the corresponding side lengths of square ABCD . What is the scale factor r ?
r=
