Explanation

The given solution is already solved:

5x + 8 = 23

5x = 23 - 8

5x = 15

x = 15/5

x = 3

Explanation

F ∝ m1m2

If both masses are doubled, F' ∝ (2m1)(2m2) = 4m1m2

So, F' is 4 times F.

Explanation

To find g(3), substitute t = 3 into the equation:

g(3) = (3)³ + (3)² - 9(3) - 9

= 27 + 9 - 27 - 9

= 0
