In a set of picture frames, frame 1 has a length that is 5 inches longer than its width, w, and frame 2 has the same length as frame 1, but is 2 inches wider than frame 1. the area of frame 2 is 28 square inches more than the area of frame 1. express these conditions into mathematical formula.

The mathematical formula would be

Step-by-step explanation:

Let the width of the frame 1 be 'w'.

Let the width of the frame 2 be 'w+2'.

Let the length of frame 1 be 'w+5'.

Let the length of frame 2 be 'w+5'.

Since the area of frame 2 is 28 square inches more than the area of frame 1.

According to question, it becomes,

Hence, the mathematical formula would be

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
