She gives away n books per week, so If 
, then she has (
) books left at any time.
this will be the explicit formula.
so we need to write in terms of recrusive.
to be recrusive each term must be expressed in terms of previous term.
in this represent ![a_{w[tex] +1](https://tex.z-dn.net/?f=%20a_%7Bw%5Btex%5D%20%2B1%20)
} [/tex] in terms of 
replace w+1 in place of w .
.
. this will be the recrusive expression for number of books she left.
is it a rectangular prism
SOLUTION:
We are to calculate the shaded area of the given shape.
CONCEPT:
This is a triangle that a rectangle was cut out from.
To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.
The shaded area = Area of the triangle - Area of the rectangle
A. Prove that QR ≅ QR by reflexive property
Nikki is going to use <em>SSS Property</em>, which is Side, Side, Side. This means that, given two pairs of sides are congruent, you will have to find out the last side, which is the same side. This means that it is congruent with itself (since both triangles share the same side), and uses the reflexive property.
hope this helps
