Answer:
Width = 6 units
Length = 12 units
Step-by-step explanation:
First thing first :)
The area of a rectangle is given by the formula:
where
is the area of the rectangle
is the width
is the length
On the other hand, the perimeter of a rectangle is given by:
where
is the perimeter
is the width
is the length
We know from our problem that the area of our rectangle is twice its perimeter, so:
We also know that its length is twice its width, so 
. Let's replace that value in our previous equation and simplify:
Subtract 
from both sides of the equation:
Factor :
Equate both factor to zero:
A length can't be zero, so discard 
and solve for the other one:
Know that we have the width of our rectangle, we can find its length:
We can conclude that the width of our rectangle is 6 units and its length is 12 units.

Answer:
2x⁴ + x³ - 3x² - 4x + 2
4
Step-by-step explanation:
Given functions:
f(x) = 2x⁴ - 3x² - 2x + 5
g(x) = x³ - 2x - 3
Unknown:
Sum of the polynomials = ?
Order of the sum = ?
Solution:
The sum of the polynomial is expressed as;
f(x) + g(x) = 2x⁴ - 3x² - 2x + 5 + x³ - 2x - 3
= 2x⁴ + x³ - 3x² - 2x - 2x + 5 -3
= 2x⁴ + x³ - 3x² - 4x + 2
The order of the sum is the highest power which 4.
This polynomial is of the 4th order.
Answer:
Line QT and QS is the geometric mean of RT because QT and QS added and divided by 2 will equal the middle of both sums.
T is the midpoint of segments QT and QS
