    300 - 100\pi \:  {cm}^{2}

    Explanation:

    Area of a rectangle:

    15 \times 20 = 300 {cm}^{2}

    Area of a circle:

    {\pi \: r}^{2} = \pi \times  (\frac{20}{2} ) \\  = \pi \times {10}^{2}  = 100\pi \: {cm}^{2}

    The area of the unshaded part:

    300 - 100\pi \:  {cm}^{2}

    answer:

    -14x

    Step-by-step explanation: because (3x-10)2=-14x

    Just do the 3-10=7

    7x2 = - 14

    Why negative because negative ten is higher that positve 3

    So basically the answer is -14x
