Answer:
c
Step-by-step explanation:
When you provide heat (thermal energy) to the gas molecules, their root mean square velocity (kinetic energy) increases, as a result they the gas exerts a higher pressure on the walls of the balloon and the balloon expands.

Answer:
20 goes into 110 five-and-a-half times
Step-by-step explanation:
Let's show our work:
20 + 20 + 20 + 20 + 20 + 10
\____\_____\____/_____/_____/
100
100
= 20 + 20 + 20 + 20 + 20 + 10
Half of 20 = 10
The keyword is half - so that leaves a 0.5 in your answer to "How many times does 20 go into 110."
How many 20's are there? Let's count!
20 + 20 + 20 + 20 + 20
1 2 3 4 5
So five 20's + one 0.5 = ?
That equals 5.5, because 5 + 0.5 = 5.5
Your answer is 5.5!
I hope this helps!

Answers:
- C) x = plus/minus 11
- B) No real solutions
- C) Two solutions
- A) One solution
- The value <u> 18 </u> goes in the first blank. The value <u> 17 </u> goes in the second blank.
========================================================
Explanations:
- Note how (11)^2 = (11)*(11) = 121 and also (-11)^2 = (-11)*(-11) = 121. The two negatives multiply to a positive. So that's why the solution is x = plus/minus 11. The plus minus breaks down into the two equations x = 11 or x = -11.
- There are no real solutions here because the left hand side can never be negative, no matter what real number you pick for x. As mentioned in problem 1, squaring -11 leads to a positive number 121. The same idea applies here as well.
- The two solutions are x = 0 and x = -2. We set each factor equal to zero through the zero product property. Then we solve each equation for x. The x+2 = 0 leads to x = -2.
- We use the zero product property here as well. We have a repeated factor, so we're only solving one equation and that is x-3 = 0 which leads to x = 3. The only root is x = 3.
- Apply the FOIL rule on (x+1)(x+17) to end up with x^2+17x+1x+17 which simplifies fully to x^2+18x+17. The middle x coefficient is 18, while the constant term is 17.
