2x³ = x • 2x², and
2x² (x + 3) = 2x³ + 6x²
Subtract this from the dividend to get a remainder of
(2x³ + 4x² - 5) - (2x³ + 6x²) = -2x² - 5
-2x² = x • (-2x), and
-2x (x + 3) = -2x² - 6x
Subtract this from the last remainder to get a new one of
(-2x² - 5) - (-2x² - 6x) = 6x - 5
6x = x • 6, and
6 (x + 3) = 6x + 18
This gives a new remainder of
(6x - 5) - (6x + 18) = -23
x does not divide -23, so we're done, leaving us with
[tex]\dfrac{2x^3+4x^2-5}{x+3}=2x^2-2x+6-\dfrac{23}{x+3}[/tex]
What is the length of the third side of the window frame below?
A. 10 inches
B. 12 units
C. 16 units
D. 20 units
Answer:
20 units
Step-by-step explanation:
a^(2)+b^(2)=c^(2)
48^(2)+b^(2)=52^(2)
2304+b^(2)=2704
2304-2304+b^(2)=2704-2304
b^(2)=400
\sqrt(b^(2))=\sqrt(400)
b=20
therefore,20 is the length of the unknown side

I don't understand why the answer is y=3x+1.
I got y =3x-6
please help me.
Answer: Answer is y= 3x+1
Step-by-step explanation:
Use point slope form y-y°=m(x-x°)
Find m, the slope: subtract the y values of the points, and divide that with the number you get when you subtract the x values of the points.
You should get m=3
Take either of the points, I’ll choose (0,1) because they are easy to use. Substitute 0 for x° and 1 for y°.
y-(1)=3(x-(0)) Substitute (0,1)
y-1=3x Simplify
y=3x+1 Add 1 to both sides and you’re done

Anthony travels from Page Az to Flagstaff Az at a rate of 60 miles per hour in 2.5 hours. How far is Flagstaff from Page?( Show your process plz)
Answer:
150 miles
Step-by-step explanation: The distance from Page to Flagstaff can be shown with the equation d = r * t, or distance = rate * time. In this case, the rate is 60 mph, and the rate is 2.5 h. Plugging that into the equation you get d = 2.5(60) = 150, giving you your distance.

solve for y: ax+by=c
Answer:
y=c-ax/b
Step-by-step explanation:
Subtract ax from both sides.
by=c−ax
Divide both sides by b
by/b=c-ax/b
Dividing by b undoes the multiplication by b.
y=c-ax/b
Answer: y=c-ax/b
Step-by-step explanation:
Subtract ax from both sides.
by=c−ax
Divide both sides by b
by/b=c-ax/b
Dividing by b undoes the multiplication by b.
y=c-ax/b

Joseph type 60 words in 1 and 1/3 minutes what is average typing speed in words per minute
Answer:
45 words per minute
Step-by-step explanation:
60 / 1 [tex]\frac{1}{3}[/tex]
45
The average typing speed of Joseph in words per minute is 45 words per minute.
What is an average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
Now it is given that,
Number of words = typed 60 words
Time taken = 1 and 1/3 minutes
⇒ Time taken = 4/3 minutes
Thus, Average typing speed = Number of words / Time taken
⇒ Average typing speed = 60 / (4/3) words per minute
⇒ Average typing speed = 45 words per minute
Thus, the average typing speed of Joseph in words per minute is 45 words per minute.
