A bookstore received 9 large boxes of books, and each large box held 15 books at the beginning of the week. The book store sold 45 books on Monday and 33 books on Tuesday. If they bought 28 more books on Wednesday, how many more books do they have by the end of Wednesday than they did before they got the shipment of books at the beginning of the week?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

what i would say the best answer is a. 40.5

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
