Question

Trapezoid EFGH has coordinates E (−3, 4), F (1, 4), G (3, 1), and H (−5, 1). Trapezoid EꞌFꞌGꞌHꞌ has coordinates Eꞌ (−12, 16), Fꞌ (4, 16), Gꞌ (12, 4), and Hꞌ (−20, 4). Trapezoid EꞌꞌFꞌꞌGꞌꞌHꞌꞌ has coordinates Eꞌꞌ (12, −16), Fꞌꞌ (−4, −16), Gꞌꞌ (−12, −4), and Hꞌꞌ (20, −4).

Answer 12

Either a or c

Answer 13

C.

Answer 14

not a because it would have been factored by a full 4. C, is factored by 1/4 so it would be less and therefore make it gradually bigger... :)
