Anyone Wanna help thanks

1. 8

2. 4

3a. -6 and -4

3b.  -1/2 and -5

Step-by-step explanation:

3a explanation:

Factor x^2+10x+24

(x+4)(x+6)

Set the factors equal to 0

x + 4 = 0

x + 6 = 0

-4 and -6

3b.

Factor left side of equation.

(2x+1)(x+5)=0

Set factors equal to 0.

2x + 1 = 0 or

x + 5 = 0

x =  −1/2

x = -5

-5 and -1/2

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
