Step-by-step explanation
Well you gave no answer choices so here are the steps and maybe you can just find out which one isn't here :)
18=2(4+x) first multiply 2 into 4+x
18=8+2x then subtract 8 from the other side
10=2x divide both sides by 2
x=5

Answer:
<em>8.3 mm</em>
Step-by-step explanation:
An enneagon is a polygon with 9 sides, also called nonagon.
In a regular polygon, all sides are congruent, so the length of any side is the perimeter divided by the number of sides.
length of a side = perimeter/number of sides
length of a side = 74.7 mm/9 = 8.3 mm
Answer:
8x + 4
Step-by-step explanation:
You just gotta distribute 4(2x+1) and it gives you the expression 8x + 4
Y=sqrt(3x+4)
3x+4 must be positive
3x+4>=0
Solving for x:
3x+4-4>=0-4
3x>=-4
3x/3>=(-4)/3
x>=-(4/3)
Domain of the function = [-(4/3), +Infinite)
Add all of the numbers up : 71xy=0
Hoped I helped!
