X - (-2) = 21 <== ur equation
x + 2 = 21
x = 21 - 2
x = 19
The answer should be the third one I believe
Yes this is correct because the line under the > means equal to or more than and sense we don’t know the value of x it would be more than 12 hope this helps please mark brainlist <3
Im pretty sure its -y^2+3y+13x-3
Answer:
Step-by-step explanation:
To complete the square, we first have to get our equation into form.
First we add 16x to both sides:
And now we subtract 62 from both sides.
We now have to add to both sides of the equation. b is 16, so this value becomes .
We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because and .
We can now take the square root of both sides.
We can now isolate x on one side by subtracting 8 from both sides.
So our solutions are
Hope this helped!
