Here you go.

I was sorta unsure how to read the last part in your question but I tried my best to interpret it

For this case we have the following quadratic equation:

x ^ 2 = 19x + 1

Rewriting we have:

x ^ 2 - 19x - 1 = 0

Then, using the quadratic formula we have:

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

Substituting values:

x =\frac{-(-19)+/-\sqrt{(-19)^2-4(1)(-1)}}{2(1)}

Rewriting:

x =\frac{19+/-\sqrt{361+4}}{2}

x =\frac{19+/-\sqrt{365}}{2}

Therefore, the solutions are given by:

x =\frac{19+\sqrt{365}}{2}

x =\frac{19-\sqrt{365}}{2}

Answer:

The solutions of the equation are:

x =\frac{19+\sqrt{365}}{2}

x =\frac{19-\sqrt{365}}{2}

What is the answer to this?
Yanka [14]
DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms. 

6=2*h

Divide 2 on both sides. 

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!

Show and explain how you found the answer to this problem. Marion read 616 pages in 14 days. If she read the same number of page
Pepsi [2]

Based on the number of pages read and the time it was read in, the number of pages read per day was <u>44 pages. </u>

Marion read 616 pages and did this in 14 days.

She read the same number of pages each day so the number of pages read per day was:

<em>= Number of pages read in total / Number of days </em>

= 616 / 14

= 44 pages

In conclusion, she read 44 pages per day.
