Step-by-step explanation:
Area = l × b
= 9ft × 8ft
= 72ft²
Answer:
x = -2
Step-by-step explanation:
14 - (x + 5) = 3(x + 9) - 10
14 - x - 5 = 3x + 27 - 10
14 - x - 5 = 3x + 17
9 - x = 3x + 17
-x = 3x + 8
-4x = 8
-x = 2
x = -2
Answer:
its a bit blurry i cant see
Step-by-step explanation:
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
