Answer:B
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
The problem can be solved geometrically. By this way, the solution is going to be easy, as well.
We can see from the attached graph that the coordinates are the vertexes.
Considering a unit distance, we can find that the width of this rectangle is:
4 = 12 - 8
and the length is:
7 = 6-(-1)
Then, the perimeter is P = (4+7)*2 = 22
Answer:
45
Step-by-step explanation:

ssubstitute a and b for any of the numbers (3 or 6) and get 36+9 which is 45
45 =

so you would need to find the square root to get c
Divide the stack into halves, if the stacks are equal, they are even. If they aren't, they are odd.
The rule is, the numbers are each going up by 2/6's
E.g. 1/6 , 3/6 (= 1/2), 5/6 , the missing number is, 1 whole and 1/6
