Form a polynomial whose zeros are -2,2,4; degree: 3

9514 1404 393

  y = x^3 -4x^2 -4x +16

Step-by-step explanation:

If r is a root, then (x -r) is a factor. A polynomial with the give roots is ...

  y = (x -(-2))(x -2)(x -4) = (x^2 -4)(x -4)

  y = x^3 -4x^2 -4x +16

x = 12

y = 15

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.
