Arectangle has a length of 4x and a width of 4x-2. it perimeter i 12 inches. find the length and width

perimeter (P ) = 2( length + width )

                     =2(4x+4x-2)

                    =2(8x-2) = 16x -4

thus 16x-4 = 12 (add 4 to both sides)

16x = 16 hence x = 1

length = 4x = 4x1 = 4 inches and width = 4x - 2 = 4-2 = 2 inches

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
