I hope the choices for the numerators of the solutions are given.

I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

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

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = 10, b = -19 and c = 6.

Next step is to plug in these values in the above formula. Therefore,

x=\frac{(-19)-\pm\sqrt{(-19)^2-4*10*6}}{2*10}

=\frac{19\pm\sqrt{361-240}}{20}

=\frac{19\pm\sqrt{121}}{20}

=\frac{19\pm11}{20}

So, x=\frac{19-11}{20} ,\frac{19+11}{20}

x=\frac{8}{20} , \frac{30}{20}

So, x= \frac{2}{5} ,\frac{3}{2}

Hope this helps you!

What is the correct value of z?<br> A. Z=12<br> B. Z=13<br> C. Z=10<br> D. Z=11
inna [77]
<h3>Answer:  A) z = 12</h3>

==========================================

Work Shown:

RS = RT

2z-15 = 9

2z = 9+15

2z = 24

z = 24/2

z = 12

The reason why RS is equal to RT in the first equation is because we have an isosceles triangle. Recall that any isosceles triangle has exactly two sides the same length, and the opposite base angles are congruent to one another. The congruent angles are indicated with the single arcs.

In short: the base angles S and T are congruent, so the opposite sides RS and RT are the same length. This leads to RS = RT.

Answer:

96 inches

Step-by-step explanation:

We can write a proportion to solve

60 inches          x inches

--------------- = -------------

5 ft                       8 ft

Using cross products

60 *8 = 5x

480 = 5x

Divide by 5

480/5 = 5x/5

96 = x

96 inches
