Best ResponseYou've already chosen the best response.1when figures are 'similar' it means they have the same 'proprtions' so all angles ar eth esame, and all ratios of edges are the same So look at the big rectancle and write the 'ratio' of th small edge to the large edge Then do the same for the small rectangle (this time you need to leave x in the proportion' these two ratios are equal to each otherso you can work out x from that

Best ResponseYou've already chosen the best response.0cause you subtracted 4 from 9 to get 5 and then do the same to the 7 and 2.98 is the closest to 3

Best ResponseYou've already chosen the best response.1yes  thoae are correct for the 2 ratios now because the rectangles are similar those ratios are equal to each other so write them as en equation (ratio 1 = ratio 2) and then find what x is..
