Algebra 1, sem. 2; show work! a rectangular flower bed is enlarged so that its area increases by 14 m². the enlarged flower bed is a rectangle and its area is x^2+9x+14 m². which expressions represent the dimensions of the flower bed before the increase? *i already know the answer is x & x+9, i need to know why*

The enlarged flower bed is a rectangle and its area is x^2+9x+14 m²

So before its enlargement by 14 m², the area of the rectangle = x^2+9x

As you know, the area of rectangle is equal length times width

so area = x^2+9x

factors:

x^2+9x = x (x + 9)

So the dimensions are x and (x + 9)

Hope it helps.

step-by-step explanation:

i think you should think about the question and not look online.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
