Answer:
either 452, 462, 472, 482, 492
Step-by-step explanation:
4 in the hundreds place -- 4??
two in the ones place -- 4?2
round to nearest hundred means tens place ≥ 5
there is not enough information to narrow it down to one number
21/40, 17/20, 29/40, 3/4, 4/5
21/40 = 10.5/20
29/40 = 14.5/20
17/20 = 13.5/20
3/4 = 15/20
4/5 = 16/20
7-x^2
