Plug in x = 12 and y = -5 into the given equation:-

3(12) - 3(-5) = 36 + 15 = 51  Not 21

So (12,-5) is not a solution.

Review:  a "solution" to an equation is a numerical value (or set of values) that makes the equation true. 

Here you are given the linear equation 3x - 3y = 21 and the point (12,-5).  If x=12 with y= -5, then (12,5) is a solution of 3x - 3y = 21.

Substituting, 3(12) - 3(-5) = 21.  Is this true or false?

36 + 15 = 21 is obviously not true.  Thus, (12, -5) is NOT a solution of 3x - 3y = 21.

Please help! (image is for question 3)
nika2105 [10]

The formula for the total sum of the inner angles of the polygon is

Sn= (n-2) 180°

1) S6= (6-2) 180 = 4*180 = 720° In the hexagon all angles are equal

α= S6/6= 720/6= 120°

2) In each polygon the sum of the external angles is 360°

3) S5= (5-2) 180 = 540° than  we can add up all angles

x+131+108+107+110=540 => x= 540-456= 84°

4) α = 360/5=72°

Good luck!!!
