Write a number that has four digits with same number in all places, such as 4,444. circle the digit with the greatest value. underline the digit with the least value. explain

Easy.

Your number would be 2,222 and you'd circle the first 2 (starting from the left) and underline the last 2(again, starting from the left).

The reason why you'd underline the last 2, is because the very last number would represent the ones place. The first 2 would be the thousands place. Meaning that 2,222 would translate to two-thousand two-hundred twenty-two.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
