Consider the trinomial 9x2 + 21x + 10. what value is placed on top of the x? what value is placed on the bottom of the x? what is the factored form of 9x2 + 21x + 10?

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.
