I NEED HELP ASAP!!!!!!!!Find the value of each variable in the parallelogram. I only need 26-28 please show your work.
Answer: Voila
Step-by-step explanation:
26. equal opposite sides
27. Alla angles must equal 360 so 101+101=202 360-202=158/2=79
28. Intersecting equal sides
29. Opposite sides p=5 and since q-3=6 then q=9
30. Opposite equal angles 2m=70 so m=35 and n=110 because 360-140=220/2= 110
31. intersecting sides k+4=11 so k=7 and m=8

The binomial (x+2) is a factor of ?
1). 2x^{2} -5+3
2). x^{2} +5x+18
3). x^{3} +5x^{2} + 18
4). x^{3} +5x+18
Answer:
4). [tex] x^{3} +5x+18 [/tex]
Step-by-step explanation:
The binomial (x+2) is a factor of [tex] x^{3} +5x+18. [/tex]
Since, (x + 2) is a factor.
So, x = - 2 is a root
Plug x = - 2 in [tex] x^{3} +5x+18 [/tex]
We find:
[tex] x^{3} +5x+18 [/tex]
[tex] =(-2)^{3} +5(-2)+18 [/tex]
[tex] =-8 - 10+18 [/tex]
[tex] = - 18+18 [/tex]
[tex] = 0 [/tex]
Since, at x = - 2 the value of the expression [tex] x^{3} +5x+18 [/tex] becomes zero.
Therefore, (x + 2) is a factor of [tex] x^{3} +5x+18 [/tex]
