Ms. peterson wrote the expression below on the chalkboard for her class. she asked the students to write an equivalent expression using no more than one
set of parentheses. 4(3x+5y+2z)+ 3(x-z)• tom wrote 12x+20y+8z • jenna wrote 5 (3x+4y+z)• chris wrote 15x+20y-5zwhich, if any, of the three students wrote an expression that is equivalent to ms. peterson’s expression?

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
