2x^{3}+30xx^{2} +72x=0 solve using zero product property
Goshia [24]

Answer:

Values of x are: x=0 or x=-3 or x=-12

Step-by-step explanation:

The equation given to solve using zero product property is 2x^3+30x^2+72x=0

Zero property rule states that if ab=0 then a=0 or b=0

Taking x common from the equation:

2x^3+30x^2+72x=0\\x(2x^2+30x+72)=0\\

Applying zero product rule

x(2x^2+30x+72)=0\\x=0 \ or \ 2x^2+30x+72=0

Now, solving 2x^2+30x+72=0

Using quadratic formula to find value of x

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Putting values

$x=\frac{-30\pm\sqrt{(30)^2-4(2)(72)}}{2(2)}$\\$x=\frac{-30\pm\sqrt{324}}{4}$\\$x=\frac{-30\pm18}{4}$\\$x=\frac{-30+18}{4} \ or \ x=\frac{-30-18}{4}$  \\x=-3 \ or \ x=-12

So, Values of x are: x=0 or x=-3 or x=-12

3.2 geometry worksheet
alekssr [168]

Answer/Step-by-step explanation:

5. 21x + 4 = 22x - 2 (corresponding angles)

Collect like terms

21x - 22x = -4 - 2

-x = -6

divide both sides by -1

x = 6

6. (x + 72) + (x + 132) = 180 (linear pair)

x + 72 + x + 132 = 180

Add like terms

2x + 204 = 180

2x = 180 - 204

2x = -24

x = -12

7. 90 = 22x + 2 (vertical angles)

90 - 2 = 22x

88 = 22x

Divide both sides by 22

4 = x

x = 4

8. 12x + 10 = 13x + 3 (vertical angles)

Collect like terms

12x - 13x = -10 + 3

-x = -7

Divide both sides by -1

x = 7

9. 17x = 16x + 5 (alternate exterior angles)

17x - 16x = 5

x = 5

✔️17x

Plug in the value of x

17(5) = 85°

10. 21x - 6 = 20x (corresponding angles)

Add like terms

21x - 20x = 6

x = 6

✔️20x

20(6) = 120°

Nata [24]
The expectation would be that the player would not get much money. 3, 4, 5, 6, 8, 9, 10, and 11 does not get a lot due to the entrance fee of $3. 20 - 3 = 17. 5 - 3 = 2.
