I don't know how you expand it but the answer is 3x + 25 unless that's expanding.
Answer:
x3+x2-14x-24
Step-by-step explanation:
Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
Let’s divide 48 by 16 to see how many cents per inch of wire. 48/16=3 so it costs 3 cents per inch of wire. now all we have to do is multiply 47 by 3, and you will get 141 cents, or $1.41.
