Answer:
12x8x10=960
Step-by-step explanation:
We can simplify this equation using logaritmic rules. logx-logb = log(x/b)
than our equation becomes.
log3((18x^3)/(2x)) = log3(144) or
log3(9x^2) = log3(144)
for x= -4 we get that left side is equal to right side
log3(9*(-4)^2) = log3(144)
but if you put that value of x=-4 in start you will get log3(18(-4)^3) which is log of negative value which is imposible. That is why x=-4 is extraneous solution.
Answer:
-2/3
Step-by-step explanation:
-2 (6a +1) + 5 <11
1) -12a-2+5 <11
2) -12a+3 <11 add -2 and 5
3) -12a < 8. subtract 3 from each side
4) a >8/-12. divide by -12 and flip the
enequality
5) a> -2/3. simplify your fraction
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Step-by-step explanation:
Diameter = 3 meters
The radius is half of diameter so,
Radius = 3 ÷ 2 = 1.5 meters
Circumference = 2πr (r is the radius)
= 2 x π x 1.5 = 9.42 meters (rounded to 3 significant figures)
Area of a circle = π
= π x 
= π x 2.25 = 7.06 meters
