Answer 2
Answer:

Final answer:

To find the sum of the polynomials, add the like terms together. The sum of the given polynomials is 10x^2 + 3x - 2.

Explanation:

To find the sum of the polynomials, you need to add the like terms together. Start by adding the coefficients of the x-squared terms, which are 8 and 2. This gives you 10x^2. Then, add the coefficients of the x-terms, which are -7 and 10. This gives you 3x. Finally, add the constant terms, which are 3 and -5. This gives you -2. So, the sum of the polynomials is 10x^2 + 3x - 2.

Company C is the correct answer!

How far does a bus travel in 2.5 hours at 65 mph?

Answers

Speed = distance / time ⇒ distance = speed × time

distance = 65 mi / h * 2.5 h = 162.5 miles

Answer:

Distance traveled = 162.5 miles

Step-by-step explanation:

a bus travel in 2.5 hours at 65 mph

The time taken to travel is 2.5 hours

Speed of the bus is 65mph

To find the distance we use formula

Distance = speed * time

speed = 65

time = 2.5

Distance = 65* 2.5 = 162.5 miles

Distance traveled = 162.5 miles
