D
Divide the whole thing by 2
2(X^2+8x-5)
X^2+8x. =5
Half of 8 is 4 sq it so you add 16
X^2+8x+16= 5+16
(X+4)^2=21

Answer:  The correct option is (D) (x+4)^2=21.

Step-by-step explanation:  We are given to select the correct equation that has the same solution as the following quadratic equation:

2x^2+16x-10=0~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be trying to apply the method of completing the square to the given equation.

From equation (i), we have

2x^2+16x-10=0\\\\\Rightarrow x^2+8x-5=0\\\\\Rightarrow x^2+2\times x\times 4+4^2-5=4^2\\\\\Rightarrow (x+4)^2=16+5\\\\\Rightarrow (x+4)^2=21.

Thus, the required equation with the same solution as the given equation si (x+4)^2=21.

Option (D) is CORRECT.

Find the value of x.
Travka [436]
In order to solve you must find the value of the blank angle. 
Here is your first equation.
126 + x = 180
Subtract 126 from both sides.
x = 54
So now add up all the angles.
x + (2x + 6) + 54 = 180
Combine like terms.
3x + 60 = 180
Subtract 60 from both sides.
3x = 120
Divide.
x = 40
Now check your answer.
40 + 2(40) + 6 + 54 = 180
40 + 80 + 6 + 54 = 180
120 + 60 = 180
180 = 180 
There is a solution. The answer is 40.
I hope this helps love! :)

What is 5(n-1)=2(n-4)-6
Shalnov [3]

Answer:

Step-by-step explanation

6n - 6 = 2 (n+1)

Simplify 2 (n+1)

6n - 6= 2n +2

Move all terms related to n to the left side of the equation

4n -6 =2

Move all terms not related to n to the right side of the equation

4n =8

Divide each term by 4 then simplify

n=2
