Answer:
it should be d
Step-by-step explanation:
The positive values of M and N are; 3.6 and 5.6 respectively.
<h3>Simultaneous equations</h3>
When S is minimum, s can be equated to 0.
On this note, it follows that the resulting equations are;
From Substitution of M = 2 +N in the second equation; it follows that;
Hence, upon solving the quadratic equation;
Therefore, the positive value of N is; 5.6 and hence,

Step-by-step explanation:
The following match
* a² + 2ab + b² and (a + b)²
* a² - b² and (a - b)(a + b)
* a² - 2ab + b² and (a - b)²
* a³ - b³ and (a - b)(a² + ab + b²)
* a³ + b³ and (a + b)(a² - ab + b²)
* y = 10x Direct variation
* xy = 18 Algorithm
* y = 4xz Joint variation
* y = 4x/z Inverse variation
Answer:
f(x) = (x + 3)² - 14
Step-by-step explanation:
f(x) = x² + 6x - 5
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 5
= (x + 3)² - 14 ← in vertex form
