Kim is sending postcards to her family. each postcard is rectangular with an area of 12 square inches, and the length is 4 inches more than the width. find the length and width of each postcard. if x represents the width of each postcard, select all of the equations that could be used to solve this problem. answer choices

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

Line ab is y = -7/5x + 56/5i don't understand  where point d comes into this.
