Answer:
x = 6
Step-by-step explanation:
Given that F is between E and G , then
EF + FG = EG , substitute values
2x - 2 + 6x = 6x + 10 , that is
8x - 2 = 6x + 10 ( subtract 6x from both sides )
2x - 2 = 10 ( add 2 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Answer:
99/100
Step-by-step explanation:
First of all recall that

Now we we will try to apply that formula for
and
.
First rewrite 
Now

First lets distribute the 5x
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i

The only one that it is not is irrational. I think this is correct and I hope it helps
Answer:
132 inches
Step-by-step explanation:
