    {15x}^{2}  + 22x - 5

    Step-by-step explanation:

    (3x+5)(5x-1)

    (3x + 5)(5x - 1) =  {15x}^{2}  - 3x + 25x - 5 \\  =  {15x}^{2}  + 22x - 5

    196

    Step-by-step explanation:

    3x + 5 = 5x - 1

    3x - 5x = -1 - 5

    -2x = -6

    -2x/-2 = -6/-2

    x = 3


    (pencils)

    3x + 5

    3(3) + 5

    9 + 5

    14 (pencils)


    (cost for each pencil)

    5x - 1

    5(3) - 1

    15 - 1

    14 (for each pencil)


    14 x 14 = 196
