    Answer:

    320

    Step-by-step explanation:

    r = 4, so 2 x 4 = 8.

    s = 6 and t = 3, so 6 x 3 = 18. 18 squared is 324.

    u = 12, so 8 + 324 – 12, which equals 320.

    Answer:

    50

    Step-by-step explanation:

    2r + st^2 – u
    2(4) + (6)(3)^2 – (12)
    (8) + (6)(9) – (12)
    (8) + (54) – (12)
    62 – 12
    50

    Final answer: 50
