It would be: 8 (x + 3) - 2x
= 8x + 24 - 2x
= 6x + 24

In short, Your Answer would be 6x + 24

Hope this helps!

Answer:

1. $\boxed{ \bold{ \huge{ \boxed{ \sf{x = 1}}}}}$

2. $\boxed{ \bold{ \huge{ \boxed{ \sf{n = - 5}}}}}$

Step-by-step explanation:

1. $\sf{ \frac{6}{x + 1} = \frac{3}{x} }$

Do cross multiplication

$\dashrightarrow{ \sf{6x = 3(x + 1)}}$

Distribute 3 through the parentheses

$\dashrightarrow{ \sf{6x = 3x + 3}}$

Move 3x to left hand side and change it's sign

$\dashrightarrow{ \sf{6x - 3x = 3}}$

Collect like terms

$\dashrightarrow{ \sf{3x = 3}}$

Divide both sides by 3

$\dashrightarrow{ \sf{ \frac{3x}{3} = \frac{3}{3} }}$

Calculate

$\dashrightarrow{ \sf{x = 1}}$

The value of x is 1

---------------------------------------------------------------------

2. $\sf{ \frac{2}{6} = \frac{2n + 8}{n - 1}}$

Do cross multiplication

$\dashrightarrow{ \sf{2(n - 1) = 6(2n + 8)}}$

Distribute 2 through the parentheses

Similarly, distribute 6 through the parentheses

$\dashrightarrow{ \sf{2n - 2 = 12n + 48}}$

Move 12n to left hand side and change it's sign

Similarly, move 48 to right hand side and change it's sign

$\dashrightarrow{ \sf{2n - 12n = 48 + 2}}$

Collect like terms

$\dashrightarrow{ \sf{ - 10n = 48 + 2}}$

Add the numbers : 48 and 2

$\dashrightarrow{ \sf{ - 10n = 50}}$

Divide both sides by -10

$\dashrightarrow{ \sf{ \frac{ - 10n}{ - 10} = \frac{50}{ - 10} }}$

Calculate

$\dashrightarrow{ \sf{n = - 5}}$

The value of n is -5 .

Hope I helped!

Best regards! :D

1 point CA If a rectangular prism has the width of 5. t What would the scale factor be? Round to Type your answer... 3 4 4 1 Giv

Sunny_sXe [5.5K]

We know that the original width was 5, and that after the enlargement the width is 45. To calculate the scale factor we divide the final width between the original one, then:

$\frac{45}{5}=9$

Therefore the scale factor is 9.

7. Which coordinate lies in the solution set for

Nana76 [90]

Answer:

The only point (0,0) lies inside the shaded region and hence it gives a solution for the set of inequalities.

Step-by-step explanation:

See the graph attached to this question.

The solution of the set of inequalities is given by the shaded region on the graph.

Now, the point (0,5) is outside this shaded region, hence it can not be the solution.

The point (3,0) also is outside this shaded region, hence it can not be the solution.

The point (-3,0) also is outside this shaded region, hence it can not be the solution.

Now, the only point (0,0) lies inside the shaded region and hence it gives a solution for the set of inequalities. (Answer)
