\underline{\underline{\large\bf{Solution:-}}}\\

\longrightarrowGiven is a quadratic equation which can be solved by splitting the middle term.

\leadstoFor this we have to look at factors of the constant term . Since here constant term term is- 6 so splitted middle term should have product equal to -6

\begin{gathered}\\\implies\quad \sf x^2-x-6=0 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf x^2-3x+2x-6=0 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf x(x-3)+2(x-3)=0 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf (x-3)(x+2) =0 \\\end{gathered}

\begin{gathered}\\\implies\quad \sf (x-3) =0 \quad or \quad (x+2) =0\\\end{gathered}

\begin{gathered}\\\implies\quad \sf x=3 \quad or \quad x= -2\\\\\end{gathered}

\quad\therefore\: \sf x  \:is \: \:3  \:or  -2

Answer: 7.5 miles

Step-by-step explanation:

think of it as a triangle; the bold line is the hypotenuse, or x.

 8   |\   x

      |_\              it's not a good triangle but you get the point

       6

and then get out pythagorean theorem: a^2+b^2=c^2

put the numbers in: 8^2 + 6^2 = x^2

do some math:

64+36=x^2

100=x^2 (and then find square root)

10=x

<u>BUT</u>, it said each unit was 3/4 of a mile, so we must multiply 10 by 3/4 to get the actual distance, which is 7.5

Ariana has a large piece of fabric that she wants to use to make some scarves. The number N of scarves she can make is inversely
AveGali [126]

Answer:

9 scarves.

Step-by-step explanation:

We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.

We know that equation of two inversely proportional quantities in in form y=\frac{k}{x}, where, k is constant of variation and y is inversely proportional to x.

Let us find constant of variation using our given information.

N=\frac{k}{A}

15=\frac{k}{3}

15*3=\frac{k}{3}*3

45=k

Now, we will substitute A=5\text{ and }k=45 in our equation to solve for N.

N=\frac{45}{5}

N=9

Therefore, Ariana can make 9 scarves.
