Answer:

Picking any one of the two books there are five shelves to put it on - which makes five ways to place it and for each of those five ways there are four shelves the other book could go such that the two books are not on the same shelf. That's four ways to place a second book for each of the five ways to place the first. That's a total of 20 ways.

The coordinate of two point P(4,6) and Q(5,-7) then find (abicissa of P) -(abicissa of Q)

grandymaker [24]

The value of (abscissa of P) -(abscissa of Q) is -1.

The given coordinates are P(4,6) and Q(5,-7).

We need to find (abscissa of P) -(abscissa of Q).

<h3>What is abscissa?</h3>

The horizontal coordinate of a point in a planar Cartesian coordinate system that is determined by measuring parallel to the x-axis is what abscissa stands for.

Now, (abscissa of P) -(abscissa of Q)=4-5=-1

Hence, the value of (abscissa of P) -(abscissa of Q) is -1.
