because the question does not specify the type of triangle. so the best is a right angled triangle.

Can anybody help me plzz

Fittoniya [83]

Answer:

1 : 12 : 4

Step-by-step explanation:

Let A, G, C represent the ages of Alex, George, and Carl, respectively. We are told that ...

A = G +12

C = 3A . . . . . . . we read this as "3 times as old"; not "3 times older"

A + G + C = 68

Substituting for G and C, we have ...

A + (A -12) +(3A) = 68

5A = 80 . . . . . add 12

A = 16 . . . . . . . divide by 5

The other ages are then ...

G = A-12 = 16 -12 = 4

C = 3A = 3·16 = 48

The ratios are ...

G : C : A = 4 : 48 : 16

G : C : A = 1 : 12 : 4

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

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