An angle bisector of a triangle divides the opposite side of the triangle into segments 8 cm and 2 cm long. A second side of the

antiseptic1488 [7]

Bisector angle

Then apply relation

8/2 = L3 / L2

L2 = 4.9

then

8/2= 4 = L3/ 4.9

So, L3 = 4•4.9 = 19.6 cm

Also

8/2= 4= 4.9/L2

So ,L2= 4.9/4 = 1.2 cm

Then, answer is OPTION D) 19.6 cm, 1.2 cm

Which two values of x are roots of the polynomial below? 3x2 - 3x + 1

Inga [223]

For this case we have the following polynomial:

$3x^2 - 3x + 1$

Applying the formula of the resolvent we have:

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

Substituting values we have:

$x=\frac{-(-3)+/-\sqrt{(-3)^2-4(3)(1)}}{2(3)}$

Rewriting we have:

$x=\frac{3+/-\sqrt{9-12}}{6}$

$x=\frac{3+/-\sqrt{-3}}{6}$

$x=\frac{3+/-i\sqrt{3}}{6}$

Therefore, the roots of the polynomial are given by:

$x=\frac{3+i\sqrt{3}}{6}$

$x=\frac{3-i\sqrt{3}}{6}$

Answer:

The values of x that are roots of the polynomial are:

$x=\frac{3+i\sqrt{3}}{6}$

$x=\frac{3-i\sqrt{3}}{6}$
