How to solve x^2>4x+3
Papessa [141]
Treat this as you would the quadratic equation x^2 - 4x - 3 + 0.   Solve this by completing the square:

x^2 - 4x + 4 - 4 - 7 = 0

(x^2 - 4x + 4) = 11

    (x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).

Graph this, using a dashed curve (not a solid curve).  Then shade the coordinate plane ABOVE the graph.

Does anyone know how to solve this? I don't even know how to start it ;-; please help, thanks
Maru [420]
These shapes are geometric, which means they're equal. XW would be the same as XY, which is 18. The same goes towards WZ. WZ = ZY, so it'll be 29. Remember, since it's geometric, each side has to equal each other

Simplify. left parenthesis negative 8 right parenthesis squared
DerKrebs [107]

Answer:

The solution of (-8)^{2} is 64.

Step-by-step explanation:

In Mathematics when two negative numbers are multiplied the result is a positive number, i.e. -a\times-b=ab.

The expression to be solved is: (-8)^{2}

Solve the above expression as follows:

(-8)^{2}=(-8)\times (-8)=64

Thus, the solution of (-8)^{2} is 64.
