Jessie is building a cabinet door, which is pictured below. The center of the cabinet door is 12 inches by 16 inches, and the border of the cabinet door has a width of x inches. The entire cabinet door has an area of exactly 396 square inches. Clockwise from the top, the picture reads, x, 12 inches, 16 inches, x, Figure not drawn to scale.

Write an equation in standard form that can be used to find x , the width of the border.

Measuring to fit a cabinet opening includes a few extra steps to get the doors made in the right sizes for your remodel or renovation:  

Measure the inside edges: When measuring the width, measure from left to right, starting with the inside edge of the left stile (vertical part of the face frame) to the inside edge of the right stile. When measuring height, measure from the inside edge of the bottom rail (horizontal part of the face frame) to the inside edge of the top rail. We build to 1/16 inch increments, so be precise.

Add space for door overlay: Cabinet doors for framed cabinets must be larger than the cabinet opening to look right and close properly. We refer to this as an "overlay". The industry standard for most cabinet doors is a 1/2 inch overlay around the cabinet door. To create a 1/2 inch door overlay on all four sides, add 1 inch to your total height, and 1 inch to your total width

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
