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 :)

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

x=half
