On donne la fonction f définie sur R par f(x) = -3x² + 152-12 1. Montrer que: f(x) - 3(x - 1)² + 27
2. Montrer que: f(x) = 3(x-1)(-+4)
3. La fonction est elle paire ou impaire ?
4. Résoudre par le calcul: f(x) < 0
5. Dresser le tableau de variations de f sur (0;5)

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.
