Answer: "possible" rational roots: ±1/5, ±3, ±1
Step-by-step explanation: Take plus or minus the factors of the constant divided by the factors of the leading coefficient.
In this case, the constant is 3, so the factors are 1 and 3, and the leading coefficient is 5, so the factors are 5 and 1.
1/5, 3/5, 1/1 and 3/1 are possibilities, simplify and attach the ± to each.
Answer:
yes i guess what is the survey?
Step-by-step explanation:
P=2L+2W
P=2*20+2*15= 40+30=70 in
A=W*L=20*15=300 in²

Remember some simle log rules
loga+logb=log(ab)
xloga=loga^x

means

also, if no base is stated, assume base 10
so
log(2x)=-1 is base 10 and translates to
10^-1=2x
1/10=2x
divide both sides by 2 aka times 1/2
1/20=x
3log(2)+log(x)=3
log(2^3)+log(x)=3
log(8)+log(x)=3
log(8x)=3
base 10
10^3=8x
1000=8x
divide both sides by 8
x=125
