Answer:

The sum of the polynomials in the equation is 3x² - 2x - 3

Step-by-step explanation:

(3 - 4x + 8x²) + (-6 + 2x - 5x²)

Distribute the positive sign to (-6 + 2x - 5x²). So all of these terms will stay the same and maintain their original signs.

3 - 4x + 8x² - 6 + 2x - 5x²

Combine like terms.

- 3 - 2x + 3x²

Now put the equation in standard form. This means that the exponential numbers will be ordered in descending order.

3x² - 2x - 3

Answer:

3x^2 -2x -3

Step-by-step explanation:

Combine like terms

3-4x+8x^2-6+2x-5x^2

Put the numbers that are squared in the front

8x^2 -5x^2 =3x^2

Put the numbers with x only next

-4x + 2x= -2x

Then the normal numbers

3-6=-3

Put them together in simplified form of the equation

Thus your answer is 3x^2 - 2x -3

Hope this helps please mark brainliest!

(09.06 HC) The function H(t) = −16t2 + 112t + 24 shows the height H(t), in feet, of a cannon ball after t seconds. A second cann
erma4kov [3.2K]
PART A:

The table of h(t) and g(t) for the value of x between 4 and 7 inclusive are shown below.

The solution for h(x)=g(x) lies between x = 4 and x = 5, this is becuase the range of value given by h(4) and h(5) and g(4) and g(5). 

The graph is shown in picture 2 to confirm this. The two functions intersect each other between x = 4 and x = 5

PART B: 

The point of intersection is the point where the cannon balls will collide.
