ABC was dilated around (–1,–3) by a scale factor of 4, then reflected over y=–x, and finally rotated 180 degrees counterclockwise , find ABC given A"(1, –5), B"(–7, 7), and C"(–7, –9)

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?

Can someone explain to me how to do
