The answer would be (18+45m) because you have to multiply the 9 to the 2 which equals 18 and then do the same for the 5m and which would be 45 because you add the variable at the end

<u>Equations with Infinite Solutions
:</u>
The systems of solving equations are methods to solve two or more linear equations in two or more variables. We generally solve systems of equations in two or three variable. To solve systems of equation in two or three variables, we need to determine first whether the equation is consistent, inconsistent, independent, or dependent. A pair of linear equations, which has a unique or infinite solutions are said to be a consistent pair of linear equations.
Answer:
4). (x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
x^2 + y^2 + 4x - 2y - 20 = 0
x^2 + 4x + y^2 - 2y = 20
Completing the square on the x and y terms:
(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20
(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1
(x + 2)^2 + (y - 1)^2 = 25.
