Answer:

x2 – x + 1

Step-by-step explanation:

if

(x4 – 3x2 + 4x – 3)/ p(x) =(x2 + x – 3),

then

(x4 – 3x2 + 4x – 3)/(x2 + x – 3)= p(x)

(x4 – 3x2 + 4x – 3)/(x2 + x – 3)=x2 – x + 1

to check this we can multiply

(x2 + x – 3)*(x2 – x + 1)=

(x2 + x – 3)*x2 - (x2 + x – 3)*(x) + (x2 + x – 3)*1=

x4+x3-3x2-x3-x2+3x+x2+8-3= x4 – 3x2 + 4x – 3

X/y=z
if we know x and z

solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y

therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
\frac{x^4-3x2 + 4x-3}{x^2+x-3}=?
solve
first factor them
\frac{(x^2+x-3)(x^2-x+1)}{x^2+x-3}=?
x^2-x+1=?
the poly is x^2-x+1

What ia the angle of AOC and DOE
natulia [17]

(i) Angle AOC would equal 48°, as it is vertically opposite to angle DOB and they are therefore equal.


(ii) Angle DOE would equal 42°. We can see this because angles on a straight line add up to 180°, and 90 + 48 = 138, so we can do 180 - 138 = 42°.


I hope this helps!

Quadrilateral ABCD is translated 6 units right and 5 units down to create quadrilateral EFGH. Determine the correct orientation
Vlad [161]

Try this suggested option (all the details are in the attachment), the correct orientation is marked with red and green colours.

P.S. The point C has coordinates: (3;1). If to traslate it 6 units right and 5 units down, then (3+6;1-5) ⇒ (9;-4). The same principle is for the others points A, B and D. Note, after translation point A is point E, B⇒F, C⇒G and D⇒H.
