Answer:
not necessarily congruent
Step-by-step explanation:
asa is angle side angle , in this case, none of the sides are marked congruent
sas is side angle side, again, no sides marked congruent
sss, side side side, again, no sides are marked congruent

Answer:
<u><em>The missing number is 31.</em></u>
Step-by-step explanation:
7+3=10
10+5=15
15+7=22
<u>The number added goes from 3 to 5 to 7, this means each time 2 is added.</u>
Therefore, the next number would be 22+(7+2) or 22+9 which equals 31.
And to check if this fits in we can plug the 31 into the sequence.
7, 10, 15, 22, 31, 42
7+3=10
10+5=15
15+7=22
22+9=31
31+(9+2)= 31+11=42
The two systems have the same solution.
The correct answer is 3) since the first equation of system B is indeed the addition of the first equation of system A and 4 times the second equation of system A.
