Answer:
z^3
Step-by-step explanation:
Z cubed is Z X Z X Z = Z^3
The perimeter of a shape is the sum of the lengths of its sides.
So, to find the perimeter of this quadrilateral, all we have to do is add the side lengths and simplify.
(x² - 6) + (2x + 5) + (x² - 3x) + (4x² + 2x)
x² + x² + 4x² + (-3x) + 2x + 2x + (-6) + 5
6x² + (-3x) + 2x + 2x + (-6) + 5
6x² + x + (-6) + 5
6x² + x + (-1)
6x² + x - 1
So, the perimeter of the quadrilateral is the quantity (6x² + x - 1).
Hope this helps!
X^2 - 3x + p = 0
x^2 + qx + 7 = 0
αβ = p..........................(1)
3α + 3β = -q..................(2)
3α3β = 9αβ = 7
so substituting for αβ from (1):-
9p = 7
p = 7/9
α + β = 3 ( from first equation)
from (2) -q = 3 (α + β)
so -q = 3*3 = 9 and q = -9
Answer is p = 7/9 and q = -9
