Answer:

1) 4

2) 1.5

3) 8

4) 1

5) 5

6) 9

Step-by-step explanation:

<h3>1)</h3><h3> √16</h3>

= √(4x4)

= √(4)²

<h3>= 4</h3>

<h3>2)</h3><h3>√2.25</h3>

= √(9/4)

= √(3x3)/(2x2)

= √(3)²/(2)²

= 3/2

<h3>= 1.5</h3>

<h3>3)</h3><h3>6² ÷ 9 x 2 </h3>

= 36 ÷ 9 x 2

= 36 x 1/9 x 2

= 36/9 x 2

= 12/3 x 2

= 4 x 2

<h3>= 8</h3>

<h3>4)</h3><h3>12-2 / 6+4</h3>

= 10/10

<h3>= 1</h3><h3 /><h3>5)</h3><h3>√(16+9)</h3>

= √(25)

= √(5x5)

= √(5)²

<h3>= 5</h3><h3 /><h3>6)</h3><h3>63 ÷ 3² + |2|</h3>

= 63 ÷ 9 + |2|

= 63/9 + |2|

= 21/3 + |2|

= 7 + |2|

<h3>= 9</h3>

How do you complete the square to rewrite y= x^ -6x + 15 in vertex form
Vaselesa [24]
Vertex form of a quadratic equation is y=a(x-h)^{2}+k
where (h, k) is the vertex. 

Our aim is to write the expression y=x^{2} -6x+15 in the form 
y=a(x-h)^{2}+k



y=x^{2} -6x+15

y=x^{2} -2*3*x+15

y=(x^{2} -2*3*x+ 3^{2})-3^{2}+ 15

y=(x-3)^{2}-9+15

y=(x-3)^{2}+6
