Simplify x2 + 10x + 9 over 2(x + 9) − (x + 9)

x+1

Step-by-step explanation:

First factor x² + 10x + 9 using the AC method.

(x +1) (x + 9)

then simplfy the denominater.

x + 9

finally cancel the factor of x + 9 from top and bottom.

the answers is x + 1.

hope this helps :)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
