anygoal [31]

Answer:

+ $\frac{9}{4}$

Step-by-step explanation:

To complete the square, with the coefficient of the x² term = 1

add ( half the coefficient of the x- term)² to both sides

x² + 3x + ( $\frac{3}{2}$ )² = 6 + ( $\frac{3}{2}$ )²

x² + 3x + $\frac{9}{4}$ = 6 + $\frac{9}{4}$

How do I solve this?

Svetradugi [14.3K]

Answer: x = 15; y = 32; z = 2.5

see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.

=> this parallelogram is a square

=> the diagonal lines of the parallelogram are perpendicular to each other

=> m∠1 = 90°

⇔ 3y - 6 = 90

⇔ 3y = 96

⇔ y = 32

because this is a square

=> 3x = 18z = 45°

=> x = 15

z = 2.5
