Find the area and perimeter of a rectangle.<br> the length is x+6 the width is x+2
yarga [219]

Answer:

<h2><u><em>Area = x² + 8x + 12</em></u></h2><h2><u><em>Perimeter = 4x + 16</em></u></h2>

Step-by-step explanation:

The area of a rectangle is given by the formula:

Area=width×height

The perimeter of a rectangle is given by the formula

Perimeter=2(width+height)

Area

(x + 6) × (x+2) =

x² + 2x + 6x + 12

x² + 8x + 12

------------------

Perimeter

2 × (x + 6 + x + 2) =

2 × (2x + 8) =

4x + 16

Easy!!!
aksik [14]

Step-by-step explanation:

f(g(10))

This is called a composite function.  It's when you plug one function into another.

First, find g(10):

g(x) = √(x-9)

g(10) = √(10-9)

g(10) = √1

g(10) = 1

Then plug that into f(x):

f(x) = -9x - 9

f(g(10)) = -9 g(10) - 9

f(g(10)) = -9 (1) - 9

f(g(10)) = -9 - 9

f(g(10)) = -18
