Apolygon has vertices a(1,1), b(1, 4), c(4, 4). this figure is dilated by a factor of 3 and center of dilation (-1, 4). find the coordinates of the polygon after dilation.

Step-by-step explanation:

New coordinate = [old coordinate - dilation center]* scale factor + dilation center

So,

For A(1,1)

For B(1,4)

For C(4,4)

Therefore these (5,-5) , (5,4) and (14,0) are the new coordinates of polygon after dilation.

what? ?

what type of question is thiss

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
