Answer: 28ins²

Step-by-step explanation:

From the question, let the width of the rectangle = xins.

Therefore, the breadth                                            = ( x + 3 )ins.

(A) The area of the rectangle which is L x B          = x( x+ 3 )

                                                                              = (x² + 3x)ins² . In polynomial.

(B) The area of the rectangle if the width is 4ins, that is if x = 4ins.To find the area, we substitute for x in the area above

                                                                             = 4² + 3 x 4

                                                                             = 16 + 12

                                                                             = 28ins²

Answer:

A - x (x+3) = Area of the rectangle

B- 28 inches squared

Step-by-step explanation:

B- using the formula from A

x = 4

x + 3 = 4 +3 = 7

4 times 7 is 28

What is the graph of the function f(x) = the quantity of x squared plus 4 x minus 12, all over x plus 6?
LenaWriter [7]
X^2 + 4x -12 = (x+6)(x-2)

so 
  (x+6)(x-2)
---------------- = x - 2
     x + 6

f(x) = x -2

answer is B.

because
if x = -6
then y = -6 - 2 = -8

(-6,-8) is the order pair
