Assuming your 10N are all intended to be 10^N, equations B, D, F are correct.
___
Your calculator can help you with this.
Answer:
T^2 = 4π^2 * L / g^2
L = T^2 * g^2 / 4*PI^2
Step-by-step explanation:
S + l. = 34
11s + 21l= 514
-11s - 11l= -374
11s + 21l = 514
10l = 140
l = 20 long sleeve shirts
s + 20 = 34
s = 14 short sleet shirts
6/8a+4,6-2/4a. I think that this is the answer.
