Answer: m=9
Step-by-step explanation: add 16 to both sides, Which gives you 36.Now you have 4m=36 ,so you divide 4 on both sides which gives you 9 .So it is m=4
6x5=30/2=(15)
2x3=6
15-6=11
11 is the answer
Answer: 1/3 sec or 0.333 sec
Step-by-step explanation:
d = 30*t^2 + 80*t = 30
putting into quadratic form, a*t^2 + b*t + c = 0
30*t^2 + 80*t - 30 = 0 where: a = 30 b = 80 c = -30
solve quadratic:
t = [-b + sqrt( b^2 - 4*a*c)]/2*a
substitute in values above
therefore, t = 1/3 sec or 0.333 sec
