I need the answer as soon as possible

Extracted text: H.W: Thirty signals, twenty of them have 4kHz bandwidth, the other have bandwidth of 3 kHz are FDM/SSB multiplexed then modulated by an RF carrier of 800 kHz using AM modulator: 1- Calculate minimum multiplexing and transmission bandwidths. 2- Calculate multiplexing and transmission bandwidths if 0.7 kHz guard band is allowed between each two signals and below the first signal.
