how are acids and protron related
Acids and protons are related because acids are substances that can donate protons. Protons are positively charged particles found in the nucleus of an atom. In the context of acids, when they dissolve in water, they release hydrogen ions (H+), which are essentially protons. Therefore, acids can be defined as proton donors.
what is the value of n so that the expression x^2+11x+n is a perfect square trinomial
To determine the value of n so that the expression x^2 + 11x + n is a perfect square trinomial, we need to take half of the coefficient of x (which is 11/2) and then square it.
So, (11/2)^2 = 121/4.
Therefore, the value of n is 121/4.
what is 121/4 in decimal form
The decimal form of 121/4 is 30.25.
what is a solution of x^2+6x=-5
To find a solution of the equation x^2 + 6x = -5, we need to set the equation equal to zero and solve for x.
Rearranging the equation, we get x^2 + 6x + 5 = 0.
Now, we can factorize the quadratic equation:
(x + 5)(x + 1) = 0.
Setting each factor equal to zero, we get:
x + 5 = 0 or x + 1 = 0.
Solving these equations, we find:
x = -5 or x = -1.
Therefore, the solutions to the equation x^2 + 6x = -5 are x = -5 and x = -1.
