When you distribute you should get
![12 {x}^{2} + 8x - 3x - 2](https://tex.z-dn.net/?f=12%20%7Bx%7D%5E%7B2%7D%20%20%2B%208x%20-%203x%20-%202)
Simplify to get
![12 {x}^{2} + 5x - 2](https://tex.z-dn.net/?f=12%20%7Bx%7D%5E%7B2%7D%20%20%2B%205x%20-%202)
Answer 2 is correct
6 wooden sticks and one long wooden border
so totally 7 wood is there
I think this correct
<span>f(x) = x</span>² <span>+ 12x + 6 </span>→ y = x² + 12x + 6<span>
Let us convert the standard form into vertex form.
1) Complete the squares. Isolate x</span>² and x terms.
<span>y - 6 = x</span>² + 12x
<span>
2) Create the perfect square trinomial. Whatever number is added on one side must also be added on the other side.
y - 6 + 36 = x</span>² + 12x + 36<span>
y + 30 = (x + 6)</span>²
<span>y = (x + 6)</span>² - 30 ← Vertex form
<span>
To check:
y = (x + 6) (x + 6) - 30
y = x</span>² + 6x + 6x + 36 - 30
<span>y = x</span>² + 12x + 6<span>
The zero that could be added to the given function is 36, -36</span>
Answer:
D. 55%
Step-by-step explanation:
The error range ± 9% means that the range is 9% below 62% or 9% above 62%.
The range is:
(62% - 9%) to (62% + 9%)
53% to 71%.
The only answer between 53% and 71% is 55%.
Answers A, B, C are all greater than 71%.
