Answer:
7 and 14
Step-by-step explanation:
5x + 3 = 38
5x = 38 + 3
5x = 35
x = 35/5
x = 7
The 30th term of this sequence would be 248
That would be the cube root of (x+5)^11.
If desired, this could be reduced to the cube root of (x+5)^9*(x+5)^2, which would be
(x+5)^3*(x+5)^(2/3)
Since the pool is square, the four sides are equal.
Therefore the length of one side = sqrt(292) = 17.1 to the nearest tenth.
