Answer:
<em>Addition Property of Equality</em>
Step-by-step explanation:
<u>System of Equations</u>
When two equations are given and two variables are unknown in both equations, then we can solve the system in several ways.
One method consists in adding both equations term by term and eliminate one of the variables. That property is called the addition of equalities. Let's consider the equations given in the problem:
If we add both equations, we have
Simplifying
By adding both equations we managed to eliminate the variable y and could easily find the value of x
Answer: Addition Property of Equality
Answer:
The correct option is c.
Step-by-step explanation:
The quotient of the polynomials is
We need to find the remainder by using long division method.
The dividend of the given expression is
The long division method is shown below.
From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
Therefore the correct option is c.
Answer:
What’s the question?
Step-by-step explanation:
Let's call the midpoint of GF M.
MF = 16/2 = 8
KF = 25.89
MK = sqrt(25.89^2 - 8^2)
MK = 24.62
MKF = 8 * 24.62 / 2 = 98.48 square units for one triangle
There are 20 of those triangles that make up the decagon.
Therefore the total area = 20(98.48) = 1969.6 which would be option C
Answer:
Step-by-step explanation:
The denominators are the same. You can add the numerators without any extra work.
The denominator factors as (2x-3)(3x+4), so there are no factors that will cancel with the numerator.
