Answer:

j₁ = - 2

j₂ = - 9

Step-by-step explanation:

j² + 11j + 18 = 0

j² + 9j + 2j + 18 = 0

j(j+ 9) + 2(j + 9) = 0

(j + 2)(j + 9) = 0

j + 2 = 0 => j₁ = - 2

j + 9 = 0 => j₂ = - 9

I need help with these please... anyone?
Svetlanka [38]
The total measure of the interior angles of each figure will be:

180 (n-2) = 180 (4 - 2) = 360

Now add all those angles and set them equal to 360.

41 + 133 + 86 + x = 360

x is the unknown angle.

260 + x = 360
x = 100

The missing angle that is Not labeled in any of the figure is 100°

Hope this helps :)

2r + 2r + 5 + r + 4r - 3 = 38

9r + 5 - 3 = 38

9r + 2 = 38

9r = 38 - 2

9r = 36

9r/9 = 36/9

r = 4cm

Done!
