Not sure about 1 and 8, I think there trapezoids but not sure.
2 is a square
3 is a rectangle
4 and 10 are a rhombus
5 and 11 are parallelograms
6 is a kite
7 is a square
can't really see 9
can't really see 12
Hope that helped.
I believe it is y axis that it is reflected by
The answer should be 31/10
Scale factor is given by:
(length of larger figure)/(length of smaller figure)=(width of larger figure)/(width of the smaller figure)=3.4
The length of the larger figure will be given by:
length=(scale factor)*(length of smaller figure)
=3.4*6=20.4 cm
width of the larger figure will be given by:
width=(scale factor)*(width of smaller figure)
=3.4*4.5
=15.3 cm
Therefore the dimension of the new parallelogram will be 20.4 cm by 15.3 cm
$20×.25=$5
$20-$5=$15
$15×.15=$2.25
$15+$2.25=$17.25
$17.25 is your answer
