3rd one: 210
4th one: 72
Step-by-step explanation:
here are the actual answers since the other person who "answered" is clearly just hungry for points
Simplify the following:
6 a b - 3 x + 2 a b
Grouping like terms, 6 a b - 3 x + 2 a b = -3 x + (6 a b + 2 a b):
-3 x + (6 a b + 2 a b)
a b 6 + a b 2 = 8 a b:
Answer: -3 x + 8 a b

Hope this helps :)
Answer:
a² + b² = 15² = 225
P = 2a + 2b = 2(a + b) = 38
P² = 4(a + b)² = 38²
4(a² + 2ab + b²) = 1444
Substitute a² + b² with 225
4(2ab + 225) = 1444
2ab + 225 = 361
2ab = 136
ab = 68 cm²
