2 answers:

6 0

Both 16 and 8 have a common factor which is 8, so divide both numbers by 8, and you get 2x-1, which is equivalent to 16x-8

Hi again. Are there options? If not then you could do 5x+10x-8+x or really any number of things since you combine like terms before you solve.

2√m^2 if m is greater than or equal to 0

iris [78.8K]

Answer:

$\displaystyle \boxed{|2m| }$

Step-by-step explanation:

we are given that

$\displaystyle 2 \sqrt{ {m}^{2} }$

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

$\displaystyle \boxed{2 |m|}$

remember that,|a|•|x|=|ax| hence,

$\displaystyle \boxed{ |2m|}$

and we're done!

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: $\frac{1}{3} *b*h$

$\frac{1}{3} *$ π $*r$ ² $*h$ =

$\frac{1}{3} *3.14*15^{2} *60=\\$

$\frac{1}{3} *3.14*225*60=$

$\frac{1}{3} *3.14*13,500=\\$

$\frac{13,500}{3} *3.14=\\$

$4500*3.14=$

14,130 feet³
