1-44. For each expression below, build a rectangle using all of the tiles, if possible. Sketch
each rectangle and label its dimensions. Write an equation that shows that the area
written as a sum (such as X^2+6x + 8) is equivalent to the area written as a product
(such as (x + 2)(x + 4)). If it is not possible to build a rectangle, explain why not.
a x^2+ 8x + 12
b. 4x^2+ 4x
C.2x² + 7x+1
d. x^2+ 2xy + y^2
с.
2r + 7x + 1
