This might be summing amplifier because there is only one op amp.

Only one op-amp is required that will be inverting amplifier working in inverting mode.

This is an summing amplifier configuration so there is three input with three input resistor and one feedback resistor and by applying superpositon theorem and KVL we can get the equation.

This is summing amplifier. One is enough.

Ya, a single opamp is required, since RF is common.

I think.

This answer is wrong. Only one op amp require to construct.
