There are 5 different coloured cups in a row. The green cup is to the left of the red cup (but not necessarily next to it).
The yellow cup is to the left of the purple cup (but not necessarily next to it).
The blue cups is on one end of the row of cups.
For all these 3 statements to be true, how many different ways could these 5 cups be arranged?

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

2x + 8

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
