Answer:
w < 7
Step-by-step explanation:
Since the inequality is an OPEN circle, that means the sign is < or >
Since the sign is going to the left that means it's < or ≤
The one that has both of these effects is <
Since the sign starts at 7, the inequality is w < 7
Step-by-step explanation:

Answer:
1. b=39.497
2. c=3.606
3. a=18.974
Step-by-step explanation:
1.
41^2-11^2=b^2
1681-121=b^2
b^=1560
b=39.497
2.
2^2+3^2=c^2
4+9=c^2
c^2=13
c=3.606
3.
21^2-9^9=a^2
441-81=a^2
a^2=360
a=18.974
Answer:
I dont really understand this notation, but it should be C or D. If the inequality includes 2, its C. If it doesn't include its D. Most likely it includes im guessing but Im not sure. So if you know how this notation works, its C or D. C for including 2 and D for excluding 2.

Answer: Probably C but can be D</u></h2>
