Ivanshal [37]3 years ago
5 0

Answer:

D. 3/19

Step-by-step explanation:

12/1 = 12

12/2 = 6

12/3 = 4

These are the only ones that make the equation true.

There are also only 19 numbers because they need to be less than 20 like the question indicated. Therefore, the answer is D.

12.
Add like terms from both trinomials:

4x^{2} + -2x^{2} = 2x^{2}
2x + -5x = -3x
-1 + 3 = 2

Combine these terms to get a new trinomial as your answer:

2x^{2} - 3x + 2


13. 
Subtract like terms from both trinomials (note that subtracting a negative is the same as adding it as a positive):

3x^{2} - 5x^{2} = -2x^{2}
-8x - -11x = -8x + 11x = 3x
-1 - -1 = -1 + 1 = 0

0 can be left out of the answer.

Combine these terms to get a binomial as your answer:

-2x^{2} + 3x

Mandarinka [93]
You need to solve this for h(t)=0

<span>-16t^2-30t+124=0

This has two solutions, one is negative that does not make sense as time cannot be negative. 
The positive solution is t=2

So the interval where it is in the air is [0;2)
