Answer:
Step-by-step explanation:
Since the divisor of is in the form of
use what is called Synthetic Division. Remember, in this formula, −c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
−1| 2 1 0 1
↓ −2 1 −1
__________
2 −1 1 0 →
You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [2x³ + x² + 1]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than the leading coefficient of your dividend, so that 2 in your quotient can be a 2x², the −x follows right behind it, and bringing up the rear, 1, giving you the quotient of 2x² - x + 1.

Answer
Find out the what is the perimeter of the rectangle .
To prove
As given
The coordinates of the vertices of a rectangle are (−3, 4) , (7, 2) , (6, −3) , and (−4, −1) .
As shown in the graph given below
Name the vertices A (−3, 4) , B(7, 2) , C(6, −3) , and D(−4, −1) .
Formula
Vertices are A (-3, 4) and B (7,2)
AB = 10.2 units (approx)
As this is the rectangles
Thus AB = CD (The opposite sides of the rectangle are equal.)
CD = 10.2 units (approx)
Now vertices are B(7, 2) and C(6, −3)
BC = 5.1 units(Approx)
As this is the rectangles
Thus BC = AD (The opposite sides of the rectangle are equal.)
AD = 5.1 units
Formula
Perimeter of a rectangle = 2 (length + Breadth)
As length = 10.2 units
Breadth = 5.1 units
Put in the formula
Perimeter of a rectangle = 2 × (10.2 + 5.1)
= 2 × 15.3
= 30.6 units.
Therefore the perimeter of a rectangle is 30.6 units .
