Answer:
8246=x+180
x=8066 miles
Step-by-step explanation:
Let the initial readings be x
The final reading is the sum of initial reading and distance covered hence
Final=Initial + distance covered
Substituting 8246 miles for the final miles and 180 miles for the distance traveled to Grandma's house
8246=x+180
Solving for x
x=8246-180=8066 miles
It’s b because you simplify it to it’s simplest form
To solve this problem you must apply the proccedure shown below:
a) You must sum terms with same exponents, therefore, you have that the sum of these two polynomials is:


b) First, you must mulitply the signs of the second polynomial by the negative sign, and them, you apply an algebraic sum. Therefore, the result is:

The answers are: a)
; b)
