Answer: -x + 2

Step-by-step explanation:

So I assume that the question would be set up like this if you are finding the sum of all 3 terms:

(x + 5) + (-4x - 2) + (2x - 1)

1) Take out parentheses

x + 5 - 4x - 2 + 2x - 1

2) Add like terms

For the x terms:

x - 4x = -3x

-3x + 2x = -x

For the other terms:

5 - 2 = 3

3 - 1 = 2

The sum of the terms is -x + 2

Is 8 a unique solution to the equation 3(x-6) = 3x/4

ladessa [460]

Answer:

yes

Step-by-step explanation:

3(x - 6) = $\frac{3x}{4}$ ( multiply both sides by 4 to clear the fraction )

12(x - 6) = 3x , distribute left side

12x - 72 = 3x ( subtract 3x from both sides )

9x - 72 = 0 ( add 72 to both sides )

9x = 72 ( divide both sides by 9 )

x = 8

x = 8 is the only solution and is therefore unique

the volume of a cylinder is given by the formula v=3.14r^2h, where r is the radius of the cylinder and h is the height. suppose

photoshop1234 [79]

we know that

The volume of a cylinder is given by the formula

$V=3.14 r^{2} h$

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

$r=x+8\\h=2x+3$

Substitute the values in the formula above

$V=3.14*(x+8)^{2}*(2x+3)$

$V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)$

therefore

the answer is

The volume of the can is equal to

$V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}$
