Someone please hurry and help with the one I missed

B

Step-by-step explanation:

The rate of change is a measure of the slope m

Calculate m using the slope formula

m =

with (x₁, y₁ ) = (- 2, 12) and (x₂, y₂ ) = (0, 3) ← 2 ordered pairs from the table

m = = = = -

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.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
