Answer:
I would divide the numerator and denominator by 2 to get it's simplest
The right side of the equation can be rewritten in terms of p as 4p (4p = 4(x^2 +6) = 4x^2 +24)
Now you have (x^2 +6)^2 - 21 = 4p
Replace (x^2 +6) with p
p^2 - 21 = 4p
Subtract 4p from each side:
p^2 - 21 -4p = 0
Rewrite the expression to get p^2 - 4p -21 = 0
D ( AC ) = 6 ( because A and C have the same y-coordinate )
d ( AB ) = √[(x2 - x1)² + (y2 - y1)²],
where A ( x1, y1 ) = ( -3, 1 ) and B ( x2, y2 ) = ( -1, 3 )
d ( AB ) = √[(-1 -(-3))² + (3 - 1 )²] = √[(-2)² + 2²] = √8 = 2√2
d ( BC ) = √[(3-(-1))² + (1-3)² =√[4² + (-2)²]= √20 = 2√5
The perimeter of ΔABC:
6 + 2√2 + 2√5 = 6 + 2 · 1.41 + 2 · 2.24 =
= 6 + 2.82 + 4.48 = 13.30
8 percent because 8 percent of 4.5 is 0.36 and you just add and you get 4.86
Well that's division.
•36 divided by 9 is equal to 4.
• 81 divided by 9 is equal to 9.
•45 divided by 5 is equal to 9.
•56 divided by 7 is equal to 8.
•42 divided by 7 is equal to 6.
