A cattle rancher has 300 yards of fencing and wants to use it to enclose (fencing needed on all four sides) a rectangular region of unused land. What dimensions would give the region of land a maximum area? ​

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
