Answer:
n=2.5
Step-by-step explanation:
First, write an equation!
n+5n-6+2n+1=15
Now, combine like terms to make things easier.
8n-5=15
Cancel -5 from the left to isolate 5n as a variable.
8n-5+5=15+5
8n=20
Now divide both sides by 8.
8n/8=20/8
n=2.5
Answer:
Step-by-step explanation:344x-5-p-0-9-but=pmc+m2 something like that
Answer:
It would be Choice C, 12.4 feet.
Step-by-step explanation:
By using Pythagoras Theorem a² + b² = c²
c²- b²= a²
13²-4²=
169 - 16 = √153
√153 = 12.3693168769
12.3693168769 ≅ 12.4
Answer: g(x)= -1/2x^2
Step-by-step explanation: since the parabola is opening downwards it would have to be a negative so all we are left with is g(x)=-2x^2 and g(x)-1/2x^2 and if we go in the calculator and type up each equations you would see our answers is g(x)=-1/2x^2
