Answer:

Step-by-step explanation:
<em>Angle sum property of triangle states that the sum of interior angles of a triangle is 180°</em>
So,

Answer:
area = 8(x + 6)
The distributive property says that the x must be added to the 6 before it is multiplied by the 8
Im notr sure but if we take the chances that the 4 sum has to be either (1.3) (3.1) (2.2) (2.2) that means its chance is 4/36 for each roll which is also 1/9 ,, we can multiply 1/9 times the roll times ( 252 ) we get =28
63+12x<15
12x<-48 (subtract 63 from both sides)
x<-4 (divide out the 12)
