Gary adds $12 to his savings each week. at week 3, gary had $60 total in his savings. how much will gary have saved after 15 wk?

$204

Step-by-step explanation: For Gary to have $60 in his savings after 3 weeks of saving $12 each week, he would originally have $24 save. So the equation to be used should be t=24+12w where t= total money saved and w= how many weeks he saved. 24+12x15=$204

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+

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)
