Solving for each equation:

A: True.

$\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12$

B: False.

$\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z$

C: True, given that y = 1

$-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7$

D: True, given that b = 6.66667

$12-1.8b+1.8b=1.8b\\12 = 1.8b$

E: True.

$\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m\\$

What is the volume of a right circular cylinder with a diameter of 46. 25 cm and a height of 18. 5 cm? Enter your answer in the

Sedbober [7]

The volume of the right circular cylinder is 31064.54 cm³.

What is the formula for the volume of cylinder?

Formula:

V = πr²h.............. Equation 1

Since,

V = Volume of the right circular cylinder

r = radius of the base of the cylinder

h = height of the cylinder.

We have given that,

r = 46.25/2 = 23.125 cm

h = 18.5 cm

π = 3.14

We have to calculate volume of right circular cylinder.

Therefore,

Substitute these values into equation 1

V = 3.14(23.125²)(18.5)

V = 31064.54 cm³

Therefore

The volume of the right circular cylinder is 31064.54 cm³.

Which expression is a linear factor of x6 +x-66?

Naddik [55]

Answer:

Option D.

Step-by-step explanation:

The given expression is

$x^6+x-66$

It is a polynomial.

(x-c) is a linear factor of polynomial p(x) if p(c)=0.

Substitute x=-1 in the given expression.

$(1)^6+(1)-66=-64\neq 0$

It means (x+1) is not a linear factor of given expression.

Substitute x=-2 in the given expression.

$(-2)^6+(-2)-66=-4\neq 0$

It means (x+2) is not a linear factor of given expression.

Substitute x=-4 in the given expression.

$(-4)^6+(-4)-66=4026\neq 0$

It means (x+4) is not a linear factor of given expression.

None of the given options are a linear factor of given expression.

Therefore, the correct option is D.
