Answer:
Step-by-step explanation:
96 maybe
w is william, c is charmaine
w = c + 3
3c + 2w = 76
substitute c + 3 for w
3c +2(c + 3) =76
3c + 2c + 6 = 76, combine the c's and subtract 6 from both sides
5c = 70
c = 14
w = c + 3
so w = 14 + 3
w = 17
Answer:
216
Step-by-step explanation:
First find the base area
0.25 * √[(5 + 6 + 5) * (-5 + 6 + 5) * (5 - 6 + 5) * (5 + 6 - 5)] = 12
Equation:
12 * (5 + 6 + 5) + (2 * 12) = 216
