Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.
Step-by-step explanation:
300 - 25 divided by 3 subtracted by 200 plus 1000 minus 350:
t + 23 > 1 subtract 23 from both sides
t + 23 - 23 > 1 - 23
t > -22
