Simple question

if a figure has been dilated by a scale factor of 2, which transformation could be used to prove the figures are similar using the aa similarity postulate?

a reflection to map at least two sides of the image to two sides of the pre-image.
a series of dilations to map at least two angles of the image to two angles of the pre-image.
a rotation to map at least two sides of the image to two sides of the pre-image.
a series of translations to map at least two angles of the image to two angles of the pre-image.

Which of the following graphs could represent a quartic function?

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
