Tatiana has some money in her savings account. she decides to add money each
week. she creates a scatter plot to compare the number of weeks to the amount of
money in her account. the equation for the trend line through the data is y = 20x +
45. what does the slope tell us?

i think it is 70

step-by-step explanation:

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.
