What is the value of X

Answer:

27=x

Step-by-step explanation:

We can use the triangle angle bisector theorem

x+8 2x-5

--------- = ------------

10 14

Using cross products

14(x+8) = 10 (2x-5)

Distribute

14x +112 = 20x -50

Subtract 14x from each side

14x-14x +112 = 20x-14x -50

112 = 6x-50

Add 50 to each side

112+50 = 6x-50+50

162 = 6x

Divide by 6

162/6 = 6x/6

27=x

Answer:

$\:$

Step-by-step explanation:

Given polynomial :

f(x) = 2x³–5x² + 5x

Let the number to be subtracted be n

(x is already in equation so, n is better)

since, 2x – 3 factor given

→

$f ( \frac{3}{2} ) = 0$

So,

$2x {}^{3} - 5x {}^{2} + 5 {x}^{2} - n$

$2x {}^{3} - 5x {}^{2} + 5x - n = 0 \\ \\ 2( \frac{3}{2} ) {}^{3} - 5( \frac{3}{2} ) {}^{2} + 5( \frac{3}{2} ) - n = 0 \\ \\ 2 \times \frac{27}{8} - 5 \times \frac{9}{4} + 5 \times \frac{3}{2} - n \: = 0 \\ \\ \frac{27}{4} - \frac{45}{4} + \frac{15}{2} - \frac{n}{1} = 0 \\ \\ 27 - 45 + 30 - 4n = 0 \\ \\ 12 - 4n \: = 0 \\ \\n = \frac{ - 12}{ - 4} \\ \\ n = > 3$
