Which equation has the solutions x=1 +-sqrt 5? x2 + 2x + 4 = 0 x2 – 2x + 4 = 0 x2 + 2x – 4 = 0 x2 – 2x – 4 = 0

D is correct.

Step-by-step explanation:

We are given the root of the equation

If we are given solution of the equation then find equation using formula.

If a and b are the solution of equation then equation would be (x-a)(x-b)=0

Here,

Equation form would be

Now we simplify the above equation to get correct option.

So, D is correct.  

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

the correct answer is x/3+10≥32

hope this !
