Answer:
6
Step-by-step explanation:
7=42 is 7*6
6=30 is 6*5
5=20 is 5*4; it's multiplied by the number below it, so 3 will be 3*2
-2|-2r-4|=-12
divide by -2
|-2r-4| = 6
we get a positive and negative solution
-2r-4 = 6 and -2r - 4 = -6
-add 4 to each side
-2r = 10 -2r = -2
divide by -2
r = -5 and r = 1
Answer r = -5 ,1
