lo que es 40 x 21 dividido por 8 redondeado al décimo más cercano muestra el trabajo, así que sé que no solo usaste una calculad

Answer:
21
*40

40
-40
<u> </u>
0
=105
<u>8 goes into 84 ten times, 84-80 =4</u>
<u>Bring down the zero make 40 which 8 goes into five times</u>
<u></u>
Step-by-step explanation:
cant be round because there no tenths place

<span>First, we want to get the +7 on the other side of the equal sign, so we subtract 7 on both sides.
</span><span>x^2 - 6x<span> - 7</span> = 7 <span>- 7
</span>x^2 - 6x - 7
Next, we use the formula
to find the axis of symmetry.
Because this is a quadratic equation, it is in the form
ax^2 + bx + c
We need to identify the a b and c values.
</span><span>ax^2 + bx + c
</span><span>(1)x^2 - 6x - 7
a = 1, b = -6 and c = -7.
Substitute the a and b values into the equation to find the axis of symmetry.
</span><span> = 
</span><span> = 
= 3
The axis of symmetry is is 3.
The axis of symmetry is also the x coordinate of our vertex.
To find the y coordinate, substitute the axis of symmetry we found into the original quadratic equation by replacing each x variable with 3.
</span><span>x^2 - 6x - 7
(3)^2 - 6(3) - 7
9 - 18 - 7
-16
The vertex is (3, -16)
</span>The domain represents all possible x-values of the parabola. Because our function will always be getting wider graphically, it will cover every possible x value. The domain is all real numbers.
The range represents all possibly y values. The parabola will always be going up, but it only goes as far down as to the minimum vertex, making the range all real numbers that are greater than or equal to −16. The range can be written as y ≥ −16.
So,
Axis of symmetry: 3
Vertex: (3, -16)
Domain: All real numbers
Range: y ≥ −16

This question is solved using proportions, as the table gives us the number of words per page given the dimensions, and the number of pages, which lets us calculate the number of words.
Doing this, we get that the story will be composed of 792,800 words.
-------------------------------------------
- According to the table, pages of dimensions 8.5in x 11in have 800 words.
- The book has 991 pages, of 8.5in x 11in dimensions.
Thus, considering that there will be 991 pages, each with 800 words, the total number of words in the story will be of:
The story will be composed of 792,800 words.
