Answer:
Monomial; Standard form: 18a^2b^2
Step-by-step explanation:

71 %
Calculate score for each paper, total them and convert to a percentage.
Paper 1 : mark = 0.65 × 120 =78
Paper 2 :mark = 0.8 ×80 = 64
Total mark = (78 + 64)/200 =142/200
Percentage score = 142/200 × 100 % = 71 %
A'B'C' is larger than ABC, so the scale factor would be a whole number, scale factor of 2.
A'B'C'is also a morrir image of ABC, notice on ABC A is on the left and B is on the right, but on A'B'C', B" is on the left and A' is on the right.
This means it was reflected across the Y axis.
The first answer is the correct one.
