Answer: -4n3+12n2+7n-9
Step-by-step explanation: it basically the opposite sign (positive or negative) switched, and the order backwards. hope that helped
The vertex form of the equation is:
y = a ( x - h )² + k
- 81 = a ( 0 - 6 )² + 27
- 81 = 36 a + 27
- 108 = 36 a
a = - 108 : 36
a = - 3
y = - 3 ( x - 6 )² + 27
y = - 3 ( x² - 12 x + 36 ) + 27
y = - 3 x² + 36 x - 108 + 27
y = - 3 x² + 36 x - 81
y = - 3 ( x² - 12 x + 27 )
x² - 12 x + 27 = 0
x² - 9 x - 3 x + 27 = 0
x ( x - 9 ) - 3 ( x - 9 ) = 0
( x - 9 ) ( x - 3 ) = 0
x 1 = 3, x 2 = 9
Answer:
The x-intercepts are ( 3, 0 ) and ( 9, 0 ).
1. Distribute
1/125 x 5n - 1/125
2. Simplify 1/125 x 5n to n/25
n/25 - 1/125

Step-by-step explanation:
Given
Required
True about area II and III
The question is incomplete; so, I will answer using general knowledge.
If the total area is:
And there are 4 areas, then;
Rewrite as:
This gives:
Collect like terms
Rewrite as:
<em>So, the sum of areas III and IV must be 14x</em>
