Answer:
B : 0.7
Step-by-step explanation:
Given:
Doug lives 7. Block away from his school.
Each block is about 265 feet long.
Question asked:
What is total round-trip distance,in miles that Doug walks to and from school each day ?
Solution:
Each block is about = 265 feet
7 Block = 
As he lives 7 block away from his school that means his round trip distance is,
7 block ( travel during going to school ) + 7 block ( when return from school )
<em>Therefore, his total round trip is 14 block, means 1855 feet + 1855 feet = 3710 feet.</em>
Now, we have to convert it into miles as here asked: (unitary method)
5280 feet = 1 mile
1 feet = 
3710 feet = 
= 
Thus, total round-trip distance,in miles that Doug walks to and from school each day is 0.7 miles.
Simplify
9x^3 - 4x + 10 + x^3 + 10x - 9
Collect like terms
(9x^3 + x^3) + (-4x + 10x) + (10 - 9)
Simplify
<u>10x^2 + 6x + 1</u>
