The measure of QS from the given line is 10
<h3>Addition postulate</h3>
From the given diagram below, we will use the following addition postulate;
QR + RS + ST =QT
Given the following parameters
RT = 15
RS = 7 , and
QT = 18
Substitute
QR + RT =QT
QR + 15 = 18
QR = 18 - 15
QR =3
Determine QS
QS = QR + RS
QS = 3 + 7
QS = 10
Hence the measure of QS from the given line is 10

Answer:
3x^11+9x^7+5x^3-x+4
Step-by-step explanation:
A polynomial written in decreasing order is a polynomial that starts with terms with the highest degree and ends with terms to the lowest degree.
First find the decreasing order of the answer:
5x^3-x+9x^7+4+3x^11
3x^11+9x^7+5x^3-x+4
The answer should be this, but I couldn't find a match for it in the answer box.

Answer:
$149.50
Step-by-step explanation:
Width = x
Length = 2x - 5
Perimeter of the room = 5x
Perimeter of the room = 2(length + width)
5x = 2{(2x-5) + x}
5x = 2(2x - 5 + x)
5x = 4x - 10 + 2x
5x = 6x - 10
5x - 6x = -10
-x = -10
x = 10
Width = x = 10
Length = 2x - 5
= 2*10 - 5
= 20 - 5
= 15
Perimeter of the room = 5x
= 5 × 10
= 50 square foot
If carpet costs $2.99 a square foot, what the total cost to carpet the living room
Total cost = $2.99 × 50
= $149.50
