David sold mugs at a crafts show. On the first day, he sold 7 mugs but lost $ 3.90 on each mug. On the second day, he raised his price and sold 5 mugs with a profit of $ 3.50 on each mug. What was his total profit or loss? Write a profit as a positive number and a loss as a negative number

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
