Answer:

Answer is c) Verify the vga cable is connected

Explanation:

No video signal means that the projector is not receiving any data from the laptop. Verifying the cable connection should be the first test you should do.

If the cable is properly connected and the projector keeps showing that error then you can move on and perform additional tests, but the first requirement for establishing a connection is that the cable is properly connected.

The assignment symbol can be combined with the arithmetic and concatenation operators to provide augmented assignment operations
uranmaximum [27]

Answer:

Yes, we can.

Explanation:

We can combine with the arithmetic and the concatenation operators to provide augmented assignment operations in the programming language Python.

This mean we can abbreviate expressions like n = n + 1

For example:

n += 10 this is equal to n = n + 10

n += "example" this is equal to n = n + "example"

In this example we have

variable = variable operator expression equal to variable operator = expression.

These arguments are often used in Python's loops.
