when (2x - 3)^2 is subtracted from 5x^2, what is the result? And how can I show the answer? Thank you x

Leni [432]

5x^2 - (2x - 3)^2 =
5x^2 - ((2x - 3)(2x - 3)) =
5x^2 - (4x^2 - 6x - 6x + 9) =
5x^2 - (4x^2 - 12x + 9) =
5x^2 - 4x^2 + 12x - 9 =
x^2 + 12x - 9 <===

In Argentina, a cow on a ranch is expected to need an average of 4200 m2

nika2105 [10]

The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.

And we are asked to find the total area of their grazing but in hectares. So, we can write:

$1 \: cow = 4200 \: {m}^{2}$

Then, for 4500 cows:

$4500 \: cows = 4200 \: {m}^{2} \times 4500$

$4500 \: cows = 18900000 \: m {}^{2}$

We know that, 1 hectares = 10000 m² = 10⁴ m²

Then let the area of the field be x in hectares:

$1 \: hectare = 10000 \: {m}^{2}$

$x \: hectare = 18900000 \: {m}^{2}$

Then, putting them in proportion, We will get:

$x = \dfrac{18900000}{10000} hectares$

$x = \boxed{ 1890 \: hectares}$

So, the total area in hectares = 1890 hectares.

And we are done !!

How do I solve this and put it in interval notation?

goblinko [34]

You cannot take the square root of a negative number so the radicals must be greater than or equal to-1.
9-10x≥0
-10x≥-9
x≤9/10

{x|x≤-10}

The graph shows the quadratic function f(x) .

Rom4ik [11]

The average rate of change is the change in y divided by the change in x...

(f(8)-f(4))/(8-4)

(4-12)/4

-8/4

-2

So the average rate of change is -2.
