Can someone help me simplify (2n + 2) + (8 + 8)
emmasim [6.3K]

Answer:

7

Step-by-step explanation:

1. Lets Combine Like Terms. The only combineable terms are 8 and 8. So if we combine them they will equal 16. And we will have (2n+2)=16

2. Let's isolate the variable. We can do this by subtracting 2 from both sides. This will come out to 2n+14.

3. Let's further isolate the variable. We can do this by dividing both sides by two, which will finally come out to n=7

Find the length of side x in simplest radical form with a rational denominator.
Klio2033 [76]

Answer:

x = \frac{\sqrt{6}}{2}

Step-by-step explanation:

Reference angle = 45°

Opposite side = x

Hypotenuse = √3

Use the following trigonometric ratios formula to find x:

sin(\theta) = \frac{opp}{hyp}

Plug in the values

sin(45) = \frac{x}{\sqrt{3}}

Multiply both sides by √3

\sqrt{3}*sin(45) = x

\sqrt{3}*\frac{\sqrt{2}}{2} = x

\frac{\sqrt{3*2}}{2} = x

\frac{\sqrt{6}}{2} = x
