A rectangular storage box is 12 in.
wide, 15 in. long, and 9 in. high. How
many square inches of colored paper
are needed to cover the surface of
the box?

846 sq. in.

Step-by-step explanation:

This is surface area. There are 6 faces. Solve each face and then add them up. In this case, first multiply 9 and 12 = 108. 108 adding 108 because there is another side with the same size. Than multiply 9 and 15. 135 times 2. 216 + 270 = 486. Next you multiply 12 and 15. 180 times 2. 486 + 360 = 846

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
