The answer is 13 ft because 39 times 4 is 156 and 156 divided by 13 is 12
For the training adaptation of maximum strength, 1 to 5 repetitions per set is recommended.
The one-repetition maximum test, also called a one-rep max or 1RM, is used to find out the heaviest weight you can lift just once.
If Maximal strength is desired, it is best achieved by performing repetitions at 85 to 100 % of the one-repetition maximum (1RM).
Formula to find the repetition is
weight used x (reps done x 0.33 + 1) = 1RM
so,
Reps done = {{1RM/weight used} - 1}/ 0.33
By this find the no of reps are recommended for maximum strength.
The maximum strength is achieved by doing the number of reps by 85 to 100% of the value of 1 RM.
So,
For the training adaptation of maximum strength, 1 to 5 repetitions per set is recommended.

Answer:
0.6t - 4.3s -2.6
Step-by-step explanation:
Given the expression
(-3.5t - 4s + 4.5) + (-7.1 - 0.3s + 4.1t)
Collect the like terms
= -3.5t+4.1t-4s-0.3s+4.5-7.1
= 0.6t - 4.3s -2.6
Hence the required expression is 0.6t - 4.3s -2.6
