"Completing the square" is a step in the solution of quadratic equations. It can be accomplished without the guesswork or trial-and-error associated with methods like factoring, and it always leads to a solution. It is the method by which the quadratic formula is derived.
Answer:

Step-by-step explanation:
Given: 
If there is a coefficient in front of a
or
, that means it becomes an exponent.

Simplify the exponent.

When there is addition between two logarithms or natural logarithms, it means they multiply together.

Answer:
In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7
Step-by-step explanation:
Answer:
The answer should be 45
Step-by-step explanation:
To get the whole are you would have to multiply the lenght with the Width and then take that answer and multiply it with the height
<u>BUT</u>
because you want the surface area, it would be just the lenght and width
15x3=45
so 45 is your answer.
Answer:
16.76°
Step-by-step explanation:
In ΔVWX, the measure of ∠X=90°, WX = 8.3 feet, and XV = 2.5 feet.
We want to find the measure of <W.
We know side length that is adjacent and opposite to <W.
We can use the tangent ratio, to find the measure of <W.
The tangent ratio is opposite over hypotenuse.


Take tangent inverse to get:
