Yes;k=-3 and y=-3x is the answer because 2 x -3 = -6 -3 x -3 = -9 and etc..
Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

Hola
Step-by-step explanation:
Answer:Paul should sell 3 paintings per hour to recover his cost.
Step-by-step explanation:
Total paintings = 32
Minimum amount to sale = 17
Paintings sold = 3
Paintings left = 17 - 3 = 14
Time left = 5 hours
Therefore, he needs to sell 14 paintings in 5 hours.
5 hours = 14 paintings
1 hour =
Rounding off to nearest whole number;
2.8 paintings = 3 paintings
