Answer:

-2x^2-3x-4

Step-by-step explanation:

We have to simplify the expression (x^2-8x+5)+(-3x^2+5x-9)

Distribute the positive sign over the parenthesis

x^2-8x+5-3x^2+5x-9

Combine the like terms

-2x^2-3x-4

Therefore, the expression after simplification is -2x^2-3x-4

Second option is correct.

3) Find the value of FD. bited F 12 12 13x - 16 E 4x+11 D​
vlada-n [284]

The Length of FD = 26 cm

According to the given information

FE = FC = 12cm

As FE, FC both are radius of circle

The tangent segments to a circle from a external point are equal

Hence

CD = ED

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27/9

x = 3

CD = 13x - 16

     = 13 × 3 - 16

     = 23 cm

ED = 4x + 11

     = 4 × 3 + 11

     = 23 cm

In Triangle FED

FE is perpendicular to ED

According to Pythagoras Theorem

FD^{2}= FE^{2}+ED^{2}

       = 12^{2}+ 23^{2}

       = 673

FD = 26 cm approx.

The Length of FD = 26 cm
