Answer:
26400 ft
Step-by-step explanation:
Answer:
x^2 + 5n = 4mx
=> x^2 - 4mx + 5n = 0
D=0 (since one root then roots are equal)
b^2-4ac = 0
(-4m)^2 - 4(1)(5n) = 0
16m^2 - 20n = 0
16m^2 = 20n
8m^2 = 10n
4m^2 = 5n
hope it helps.......
D=an-am/n-m
d=a64-a3/64-3
d=3725-126/61=59
a3=a1+2d
126=a1+118
a1=8
T=PV/K
Starting with V=KT/P, multiply P on both sides to get PV=KT
Then divide K on both sides to leave T alone
And you get.....T =PV/K
A=LW
L=5+2W
A=50
50=LW
sub 2W+5 for L
50=(2W+5)W
answer is the 3rd equation
