Use the commutative property to reorder the terms
2x-29x-132=0
Next step
Collect like terms
-27x-132=0
Move the constant to the right-hand side and change its sign
-27x=132
Divide both sides of the equation by
Solution or answer ———
X= - 44/9
Alternative form <———
X =-4 8/9 ,x=-4.8
Any of those are the answer
Answer:
9n+18(2n-6)+13
Step-by-step explanation:
First, use distributive property to eliminate the parenthesis:
9n + 18(2n -6) + 13
9n + 36n - 108 + 13
Next, combine like terms:
9n + 36n - 108 + 13
45n - 108 + 13
45n + 121
Hope this helps!!

Answer:
n=3
Step-by-step explanation:
-4n-40=-2(7n+5)
Distribute the -2
-4n -40 = -14n -10
Add 14n to each side
-4n+14n -40 = -14n +14n-10
10n -40 = -10
Add 40 to each side
10n -40+40 = -10+40
10n = 30
Divide each side by 10
10n/10=30/10
n =3
18.85 feet in distance
24.13 is the circumference
(not for sure though)
Answer:
exact arc length = 21pi
approximate arc length (using calculator) = 65.9734457253857
approximate arc length (using 3.14 for pi) = 65.94
units are in feet
============================================
Work Shown:
L = (x/360)*2*pi*r
L = (315/360)*2*pi*12
L = 21pi = exact arc length in terms of pi
If you use your calculator's stored version of pi, then L is approximately
L = 21pi
L = 65.9734457253857
Or if you end up using pi = 3.14, then
L = 21*pi
L = 21*3.14
L = 65.94
Fairly close to the other approximation though a bit off because pi = 3.14 is just a rough approximation.
