Best ResponseYou've already chosen the best response.0let x and y be length and width of the rectangel. y = 3/4 x when x and y are increased by 2cm perimeter becomes 50 cm 50= 2 ( (x+2) + ( 3/4x +2) ) 50 = 2 ( 7x/2 + 4) 50 = 7x + 8 7x = 42 x=6 length, width = 9/2 cm

Best ResponseYou've already chosen the best response.0Perimeter would equal 2L + 2W then P= 2*6 + 2*( 9/2) P=12+9=21 Shouldn't it be 50? What am I missing or is the solution wrong!

Best ResponseYou've already chosen the best response.0i'm sorry i made a small error in the previous one 50 = 2( 7x/4 +4 ) 50 = 7x/2 +8 7x/2 = 42 x= 12, y = 9 please note the corrections

Best ResponseYou've already chosen the best response.0Women’s records in the women’s 1500m run. The formula R =−0.0026? + 4.0807 can be used to predict the world record, in minutes, for the 1500m run t years after 1900. Determine (in terms of an inequality) those years for which the world record will be less than 3.8 min.
