Here is a shape. all the measurements are in metres. the area of the shape is am2. find a formula for a in terms of x.

There are 3 vertical sides here.  The longest and the  is 2x + 1, and the unmarked side is (2x + 1) - x = x + 1.

Draw a horiz. line thru and parallel to the shortest horiz. line.  This line which you have drawn separates the figure into two rectangles.

The area of the smaller rectangle is 5x.  The area of the larger rectangle is (x+1)*8.  Thus, the total area of the figure is A = 5x + 8x + 8, or

A = 13x + 8 (answer)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
