3x3-27x=0<br> Solve by factoring a
Eddi Din [679]

After factoring 3x^3-27x=0 the solutions are x=0 , x=3, x= -3

Step-by-step explanation:

We need to solve by factoring:

3x^3-27x=0

Solving:

3x^3-27x=0

Taking 3x common:

3x(x^2-9)=0

Now using formula a^2-b^2=(a-b)(a+b)

3x((x)^2-(3)^2)=0\\3x(x-3)(x+3)=0

3x=0\,\,and\,\,x+3=0\,\,and\,\,x-3=0\\x=0\,\,and\,\,x=-3\,\,and\,\,x=3\\

So, After factoring 3x^3-27x=0 the solutions are x=0 , x=3, x= -3

To the nearest hundredth, what is the value of x?<br><br> 42.15<br> 43.11<br> 52.07<br> 54.26
Gnesinka [82]

Answer:

52.07

Step-by-step explanation:

sin of an angle is the opposite side over the hypotenuse

sin 51 = x/67

Multiply each side by 67

67 sin 51 = x

52.06877942 =x

Rounding to the nearest hundredth

52.07 =x
