So 4*3 = 12.
There are 12 outcomes. The answer would be D.
Hope this helps !

Answer:
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2 where r is the radius of the circle and (h,k) is the coordinates of the center of the circle. We can see that the radius is 3 units and we are given the location of the center as (-3,1) so
(x+3)^2+(y-1)^2=9
Answer:5 by 8 by 5 by 8
Step-by-step explanation: the perimeter is 26 and one side if 5 so you know that another side is also 5. So add 5 and 5 together you get 10. Then subtract 10 from the perimeter(witch we know is 26) and you end up with 16. we know that the last two side lengths are the same so divide 16 by two and the sidle length is 8.
Answer:
b = 10 mm
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
given A = 30 and h = 6 , then
b × 6 = 30 , that is
3b = 30 ( divide both sides by 3 )
b = 10
