Step-by-step explanation:

Let AB be 5cm

AC be 13cm

According to Pyathagros therom

AC²=AB²+BC²

13²=5²+BC²

169=25+BC²

BC²=169-25

BC²=144

BC=√144

BC=12cm

Area of ∆ABC=½×base×hight

=½×12×5

=½×60

=30cm²

Parimeter of ∆ABC=a+b+c

=5+12+13

=30cm

Use the quadratic formula to solve the equation x^2-7x-6=0

olganol [36]

Answer:

$\frac{7\pm\sqrt{73}} {2}$

Explanation:

We have been given with the quadratic equation $x^2-7x-6=0$

We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

$D=b^{2}-4ac$

and after that to find the variable suppose x we have the formula

$x=\frac{-b\pm\sqrt{D}} {2a}$

And general quadratic equation is

$ax^2+bx+c=0$

On comparing the given quadratic equation with genral quadratic equation we will have values

a=1, b=-7 and c=-6

After substituting these values in the formula we will get

$D=(-7)^2-4(1)(-6)={73}$

After substituting in the formula to find x we will get

$\frac{-(-7)\pm\sqrt{73}} {2}= \frac{7\pm\sqrt{73}} {2}$
