answer: a, c

Explanation:
if a < 7 or a is less than 7
a.) a < 17 a is less than 17 so that’s true
b.) -a < -7 i’m not sure on this one but i believe no
c.) 3a + 4 < 25
-4 -4
3a < 21
/3 /3
a < 7 which is true
d.) a^2 < 49 i’m also not sure how to cancel out exponents but i hope the two definite answers help
