Given that 110ₓ = 40₅ , find the value of x.
MrRa [10]

Answer:

x = 4

Step-by-step explanation:

110ₓ = 40₅    --------- change all to base ten.

<u>the system called binary</u>

1x²+1x ¹+0x⁰ = 45¹+0*5⁰

x² + x + 0 = 20

x² + x – 20 = 0

solve x using Quadratic equation

        -1 ± \sqrt{1^2 - 4* 1 (-20)}

x =  ------------------------------------

                        2 * 1

x = -5;  x = 4

therefore, x = 4

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
r-ruslan [8.4K]

Given:

The given quadratic equation is:

12a^2+9a+7=0

To find:

The solution for the given quadratic equation in simplest form by using the quadratic formula.

Solution:

Consider a quadratic equation is defined as ax^2+bx+c=0, then the quadratic formula is:

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

The given quadratic equation is:

12a^2+9a+7=0

We have, a=12,b=9,c=7. Using the quadratic formula, we get

x=\dfrac{-(9)\pm \sqrt{(9)^2-4(12)(7)}}{2(12)}

x=\dfrac{-9\pm \sqrt{81-336}}{24}

x=\dfrac{-9\pm \sqrt{-255}}{24}

x=\dfrac{-9\pm i\sqrt{255}}{24}              [\because \sqrt{-a}=i\sqrt{a}]

The solutions of the given equations are x=\dfrac{-9-i\sqrt{255}}{24} and x=\dfrac{-9+i\sqrt{255}}{24}.

Hence, the correct option is B.
