A. 12•8=96, 96/2=48, 48•4=192, 12•12=144, 192+144=336
Step-by-step explanation:
Adjacent angles.
......
Let the two ages be j and m, respectively. Then j+m>32.
Solving for Mary's age, we get m > 32 - j. Because j = m + 2, m > 32 - (m+2).
Continue solving for m: Adding m to both sides of this inequality results in
2m > 32 - 2. Then 2m > 30, and m > 15. Mary's age is greater than 15.
