How to do
15-x=-2x+6

-9

Step-by-step explanation:

15-x=-2x+6

First add -2x to the other side:

15-x+2x=6

15-x=6

Subtract 15 on the other side:

15-15-x=6-15

x=-9

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.
