Acertain quadrilateral has three sides of equal length and its perimeter is 19 cm. find all integral possibilities for the lengths of the sides in centime- ters. (hint: the sum of the lengths of any three sides of a quadrilateral must exceed the length of the fourth side.)

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.
