Answer:
5n^2+(4n)-1
Step-by-step explanation:
(5n-1)(n+1)=0
Lets find <em>n.</em>
(5n-1)(n+1)=0
FOIL it.
5n^2+5n-1n-1
Add/Substract similar factors
5n^2+(5n-1n)-1
5n^2+(4n)-1
Thats your answer.
The area of the polygon is 25.5 square units
<h3>How to determine the area of the polygon?</h3>
From the figure, we have the following coordinates
A = (-2, 1)
B = (3, 2)
C = (5, -3)
D = (-1, -3)
The area of the polygon is then calculated as:
A = 0.5 * |(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y4 - x4y3) + (x4y1 - x1y4)|
Substitute the known values in the above equation
Area = 0.5 * |(-2 * 2 - 3 * 1) + (3 * -3 - 5 * 2) + (5 * -3 + 1 * -3) + (-1 * 1 + 2 * -3)|
Evaluate the sum of products
Area = 0.5 * |-51|
Remove the absolute bracket
Area = 0.5 * 51
Evaluate the product
Area = 25.5
Hence, the area of the polygon is 25.5 square units

-5 is the answer to your question.
Answer:
option B and option D
0 and 2
Step-by-step explanation:
Given in the question two functions
f(x) = x² - 4x + 3
g(x) = -x² + 3
f(x) = g(x)
x² - 4x + 3 = - x² + 3
Rearrange the like terms, x terms to the left and constant term to the right.
x²+ x² - 4x = 3 - 3
2x² - 4x = 0
Divide by two
2x²/2 - 4x/2 = 0/2
x² - 2x = 0
Take x as a common term
x(x-2) = 0
so
x = 0
or
(x-2) = 0
x = 2
