In the top row of an chessboard, Tom writes the values 1, 2, 4, 8, 16, 32, 64, 128. In the leftmost column, Tom writes the value
s 1, 3, 9, 27, 81, 243, 729, 2187. In every other square that doesn't have a number yet, Tom writes the product of the leftmost number in that square's row and the topmost number in that square's column. What is the sum of all the numbers on the chessboard?

Answer:
Step-by-step explanation:
(5,4) ; (-3, -2)

(5,4) & m = (3/4)
y -y1 = m(x-x1)
y - 4 = (3/4)(x - 5)

#8 you do 360= 112+136+x... then you solve for x. X=112. Now you divide this by two since it is an inscribed angle. For #9 I have this very simplified work in the picture. Sorry I did not do #10
Answer:

= (x - 2) / 7 (x - 2) (x - 2)
= 1 / 7 (x - 2)
