In an investigation, Detective Tracy discovered a photograph that showed his number one suspect at the scene of the crime. To get a better look, he enlarge
the picture by a scale factor of 4/1 If the original photo measured 3 inches by 6
nches, what were the dimensions of the enlargement?

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
