Which phrase is represented by the expression 5x ( 36+ 9)?

225x

Step-by-step explanation:

Use distribution to get rid of the parenthesis.

5x * 36 + 5x*9

180x + 45x

Now combine like terms

225x

42 inches then 10 1/2 deep

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
