Answer:
y = (x + 1) (x - 1) (x - 3)
Use the distributive property to multiply x+1 by x-1 and combine like terms.
y = (x² - 1) (x - 3)
Use the distributive property to multiply x² - 1 by x - 3.
<u>y = x³ - 3x² - x + 3.</u>

how would i do this? find the perimeter of a rectangle if three of its verticles are (5,-3),(-3,-2)and(-3,3)
1 answer:
Answer:
Perimeter of rectangle = 2√65 + 10
Step-by-step explanation:
From the attached graph, we can find that:
Points (-3,3) and (-3,-2) represents the width of rectangle.
And points (-3,-2)and (5,-3) represents the length of rectangle.
Now, By using distance formula we can find the length and width of rectangle.
Length = √ ((5-(-3))² + (-3 -(-2))²) = √( 8² + 1²) = √ 65
Width = √((-3 -(-3))²+(-2-3)²) = √(0² + 5²) = 5
so perimeter of rectangle will be:
Perimeter = 2(Length + width)
Perimeter = 2( √65 + 5)
Perimeter = 2√65 + 10
