6 over 9
Step-by-step explanation:
y2-y1 over x2-x1
The perimeter is the sum of all the sides so we can add all the sides and set it equal to 35:

Now we have a quadratic so we can use the quadratic formula to find x=

. Now you can plug that into each x to find each side:-)
<span>i think the maximum length of the figure would be : 6
The total blocks that exist to form should be 8

but we can use the first blocks as the foundation for the additional length. The figure would look like this :
O
O
OOOOOO ---------> total of 8 blocks</span>
4x+5y=-12 (1)
-4x+6y=-32 (2)
(1)+(2)=> 11y=-44
y=-4
so A : -4
