Given :

  • -3x² - 9x + 12 = 0

To find :-

  • Value of x .

Solution :-

Given equation ,

  • -( 3x² + 9x -12 ) = 0
  • 3x² + 9x - 12 = 0
  • 3x² + 12x - 3x - 12 = 0
  • 3x ( x +4) -3( x +4) = 0
  • (3x -3)(x +4) = 0
  • x = 3/3 , -4
  • x = 1 , -4

Alsion saves $29.26 each month. How many months will it take her to save enough money to buy a stereo for $339.12?
Darya [45]

Answer: 12 months (1 year)

We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12

You want to divide $339.12 with $29.26 to find the total months.

339.12 / 29.26 = 11.6

CHECK:

You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.

29.26 * 12 = 351.12

It will take Alision 12 months (1 year) to buy her stereo.

Answer:

<em>The second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>

Step-by-step explanation:

We can't confirm the length of these diagonals based on the appearance of the figure, so let us apply Pythagorean Theorem;

This diagonal divides each figure ( square + rectangle ) into two congruent, right angle triangles ⇒ from which we may apply Pythagorean Theorem, where the diagonal acts as the hypotenuse;

5^2 + 5^2 = x^2 ⇒ x is the length of the diagonal,

25 + 25 = x^2,

x^2 = 50,

x = √50

Now the same procedure can be applied to this other quadrilateral;

3^2 + 7^2 = x^2 ⇒ x is the length of the diagonal,

9 + 49 = x^2,

x^2 = 58,

x = √58

<em>Therefore the second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>
