BE= 6. I had this question not too long ago. Hope this helps. :)
A model shows the visualize of what you need to do in order to complete the problem your asked. It can also show important steps and make it easier for you to answer the question, like length×height×width.
You can use pythagorean theorem and square 1.5 and 6 and those added together is the hypotenuse (the slope) squared. the answer is approximately 6.2
Well it will be a simple as grid algebra
3(2+12)+12x5
If you do 2/29 you get 0.0689 . . .
that rounds to 0.07
0.07 = 7/100 = 7%
Answer: 7%
