Answer:
I think you would have to do 2(x+4)+2(x+8) because it it talking about perimeter and if you imagine a square or rectangle, there are four sides, so just adding x+4 and x+8 wont be the whole perimeter. So, if you solve the expression 2(x+4)+2(x+8) it will give you 4x+24 XD
Step-by-step explanation:
If do the math as is shown to you will get -49.84 that I will show you its right @TTSSPony2002 so you do the math like this 3.56*-14= -49.84

The length of the railroad is 1km and it expands 10cm. To solve this problem, you have to create a right triangle. You can do this by cutting everything in half. Your hypotenuse will be 1/2km + 5cm, one of the legs will be 1/2km. To make everything simple, I converted everything into meters. So you will have 500m + .05m as the hypotenuse and 500m as one of the legs. Use the Pythagorean theorem to solve for the other leg. Do not round your answer. My teacher emailed me a hint to answering the question. She cahnged everything to meters.
use Pythagoras theorem to solve for the other leg. that is your answer. Your teacher spelled it out for you.
