Answer:
42mm
Step-by-step explanation:
For the perimeter of a shape you would add all the sides together. So in this case it would be:
7mm+7mm+7mm+7mm+7mm+7mm=42mm
Answer: 3 • ? = -6
Reasoning: -6/ 3 = -2
3 • -2 = -6
right angle because its always perpendicular to the floor
Since the co-efficient or "r" is "-3" and "-3", it will simplify to "-6" as -3-3= -6.
then the two constant terms with are "7" and "-12" will simplify to "-5" as 7-12=-5. therefore, the simplest form is -6r -5
