The scale factor being larger than 1 means we have an enlargement.
The image is going to be larger compared to the preimage.
The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4
The image rectangle is 16.8 inches by 8.4 inches
Work is in the attached picture. Whenever you are given a problem like this, draw it out. It makes it a lot easier!
The house is 25 feet tall.
20,40,60,80,100,120,140,160,180,200,220,240...
So 15h - 0.5 - 3h + 2k + 23
Add common terms
12h -0.5 + 2k + 23 (I added 15h and -3h)
12h + 22.5 + 2k ( I added 23 and -0.5)
the answer should be
12h + 22.5 + 2k
