Solve the radical equation x – 7 = square root of -4x+28. which statement is true about the solutions to the radical equation? there are no true solutions. there are two true solutions. there is one extraneous solution, with a value greater than 4. there is one true solution, with a value greater than 6.

x = 3 and 7

There are two true solutions.

Step-by-step explanation:

To solve , use inverse operations by squaring both sides of the equal sign.

The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.

(x - 3) ( x - 7) = 0

x-3 = 0 so x=3

x-7 = 0 so x=7

Now check each solution into the original equation to be sure it solve the solution and is not extraneous.

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
