1. examine the following drawing. show the sum of the of areas of the four smaller rectangles and the sum of the large rectangle in your own words explain why this is so.
! needed asap!

The areas of the smaller rectangles:

The area of the large rectangle:

The area of the large rectangle is equal of the sum of the areas of the smaller rectangle. Therefore:

It's the distributive property:

replace in by A , giving .

Then the formula

gives, on back-substitution, the formula

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

lockers 1, 4, 9, 16, 25, 40, and 49 are open
