6. what type of angle pair are lsm and osn?
1. adjacent angles

2.linear pair

3.complementary angles

4.vertical angles

7. what type of angle pair are lms and smn?
1.adjacent angles

2.linear pair

3.complementary angles

4.vertical angles

8. what type of angle pair are nsm and msl?
1. obtuse

2. linear pair

3. complementary angles

4. vertical angles

6) Vertical angles

7) Linear pair

8) Linear pair

Step-by-step explanation:

Since we have given that

6) ∠LSM and ∠OSN

The type of angle pair would vertically opposite angles.

As only one vertex is common So, it would be vertically opposites angles.

Hence, Option '4' is correct.

7) ∠LMS and ∠SMN are linear pair as it has two vertex in common.

Hence, Option '2' is correct.

8) ∠NSM and ∠MSL are linear pair as it has again two vertex in common.

Hence, Option '2' is correct.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
