Question 767258: Have mercy on me please!

SQRT(x + 8) + SQRT(x + 15) = SQRT(9x + 40)
A x = 1
Bx = 1, 4.24444
Cx = 4.24444
Dx = 1, -4.24444
E x = -4.24444
F x = -1

10. Find the volume of a cube on which the diagonal of a face measures 2.

C12
D2 SQRT(2)
E 4
F 6 SQRT(2)

The swing of a pendulum is shown by the equation: S = 6.28SQRT(L/32) where S is the time in seconds the pendulum takes to make a full swing (back and forth) and L is the length of the pendulum in feet.
11. How many seconds will a full swing take if the length of the pendulum is 4 feet?
A s = .02
Bs = 22
Cs = .125
Ds = 24
E s = 2.2
F s = 25.12

12. How long is the pendulum if it takes 5 seconds to make a full swing?
A L = 12.4 cm
BL = 30.1 ft
CL = 20.3 cm
DL = 20.3 ft
E L = 30.1 cm
F L = 12.4 ft
