Question

2r + st^2 - u, if r = 4, s = 6, t = 3, and u = 12

Answer 1

Answer:

50

Explanation:

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

Final answer: 50

Answer 2

320

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.
