Answer:
Therefore the results from adding the equation in this system is

Step-by-step explanation:
Given:
Equations as
.......................1
.......................2
To Find :
Result when adding equation 1 and 2 = ?
Solution
On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below
11x - 3y = -17
-4x + 3y = - 18
-------------------------------------------
7x + 0 = - 35
---------------------------------------------
Therefore the results from adding the equation in this system is

Answer:
(3,2) just use a slope triangle (over 2 up 3) and do it in reverse
Answer:
<em>B. (U+V)(U-V)</em>
Step-by-step explanation:
<u>Factoring</u>
The given expression is:

It should be noted that both terms are perfect squares:


Since it's a difference of squares, we need to use the following pattern to factor the required expression:

Thus, the answer is
B. (U+V)(U-V)
Step-by-step explanation:
a =2πr^2
=2π8m^2
=2π64m^2
=128πm^2
