You would need to distribute the 3t to the value in the parentheses to make the expression, aka answer, 12t^2-3t
Answer:
![4ft *\frac{12in}{1 ft}= 48 in](https://tex.z-dn.net/?f=%204ft%20%2A%5Cfrac%7B12in%7D%7B1%20ft%7D%3D%2048%20in)
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
![Scale = \frac{48 in}{6in}= 8](https://tex.z-dn.net/?f=%20Scale%20%3D%20%5Cfrac%7B48%20in%7D%7B6in%7D%3D%208)
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
Step-by-step explanation:
For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:
![4ft *\frac{12in}{1 ft}= 48 in](https://tex.z-dn.net/?f=%204ft%20%2A%5Cfrac%7B12in%7D%7B1%20ft%7D%3D%2048%20in)
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
![Scale = \frac{48 in}{6in}= 8](https://tex.z-dn.net/?f=%20Scale%20%3D%20%5Cfrac%7B48%20in%7D%7B6in%7D%3D%208)
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
