Answer:
Step-by-step explanation:
<u>Factoring the given expression:</u>
- -45x³ - 60x² - 20x =
- -5x(9x² + 12x + 4) =
- -5x(9x² + 6x + 6x + 4) =
- -5x(3x(3x + 2) + 2(3x + 2))
- -5x(3x + 2)(3x + 2)
- or
- -5x(3x+2)²
Answer: 9/8
Step-by-step explanation:
The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.
The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?
Anyways hope this helped!
To find the input value that produces the same output value for the two functions on the graph, it is the x<span> coordinate where the two graphs touch. So, for the given graph above, the value which is on the x coordinate is -2. Thus, the answer is x = -2. </span>
Answer:
4x²
Step-by-step explanation:
Your equation is 4x² - 6x² + 7x² - 20x² + 19x².
Since they all have the same variable, simply combine them all to find your answer.
4x² - 6x² + 7x² - 20x² + 19x²
-2x² + 7x² - 20x² + 19x²
5x² - 20x² + 19x²
-15x² + 19x²
4x²
