6x^2 should be one of them if i am not mistaken!
5 (2f+3)=2(5f-1)
10f+15=10f-2
10f-10f=-2-15
f=-17
Because 4x2 = 8, so 4x7=28, then you times 28 by 2 which equals 56 and 8x7=56
Answer: C
Step-by-step explanation: all real numbers can solve this problem
Answer:
Simplified: -4a²b²+18a³-2b³
3a(6a²-4ab²)+8a²b²-2b³
Multiply 3a by 6a² and-4ab²
18a³-12a²b²+8a²b²-2b³
combine like terms (-12a²b² and 8a²b²)
-4a²b²+18a³-2b³
Hope this helps
