Answer:

Step-by-step explanation:

∠ 5 and ∠ 8 are adjacent angles and are supplementary, sum to 180° , then

∠ 8 + ∠ 5 = 180°

∠ 8 + 45° = 180° ( subtract 45° from both sides )

∠ 8 = 135° → C

Step-by-step explanation:

$= (x + y)(x + 6y)$

$= x \times x + x \times 6y + y \times x + y \times 6y$

$= {x}^{2} + 6xy + xy + 6 {y}^{2}$

$= {x}^{2} + 7xy + 6 {y}^{2}$

How to find the maximum or minimum value of a quadratic function?

kipiarov [429]

Answer:

Vertex form

Step-by-step explanation:

You convert to vertex form a(x - b)^2 + c . The coordinates of the maxm/minm will be (b, c).

For example find minimum value of x^2 + 5x - 6:-

x^2 + 5x - 6

= (x + 2.5)^2 - 6.25 - 6

= (x + 2.5)^2 - 12.25

The coordinates of minimumm will be (-2.5, -12.25) The values of the minimum of the function is -12.25
