You can again ignore the parenthesis because you are not distributing anything.
Your equation will look like this
3x + 11 + 6x
You can move each of these numbers around any way you like. You can combine the 3x and the 6x if you want, but they did not do that. You cannot take the x away and put it in front of the 11 though.
B. is your answer. All they did was move the 6x inside the parenthesis and the 11 out of the parenthesis.
Always remember, when you are adding things together, the parenthesis don't matter!
Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio

Hence The height of tree house is 70.71 feet
If your just looking for x then x=2
Answer:
a=ln(28.37)
Step-by-step explanation:
e^a=28.37
Take ln both sides
ln(e^a)=ln(28.37)
a=ln(28.37)
Answer:
<h3>n>-5/2</h3>
Step-by-step explanation:
First, you have to isolate it on one side of the equation. Remember that, isolate n on one side of the equation.
6n-3>-18
6n-3+3>-18+3 (Add 3 from both sides.)
-18+3 (Solve.)
-18+3=-15
6n>-15
6n/6>-15/6 (Divide by 6 from both sides.)
-15/6 (Solve.)
-15/6=-5/2
n>-5/2
In conclusion, the correct answer is n>-5/2.
