The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). if area = length × width, what is the width of the rectangle? x 1 x – 9 x 4 x – 1
Answers
Answer:
Area = x4 + 4x3 + 3x2 - 4x - 4
Length = x3 +5x2 + 8x + 4
Width = Area / Length.
Performing long division with polynomial.
x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1
Width = x-1
Step-by-step explanation:
The value of the width of the rectangle is,
⇒ (x - 1)
We have to given that;
In a rectangle;
Area = x⁴ + 4x³ + 3x² - 4x - 4
Length = x³ +5x² + 8x + 4
We know that;
Width = Area / Length.
Hence, Performing long division with polynomial.
Width = x⁴ + 4x³ + 3x² - 4x - 4 / x³ +5x² + 8x + 4
= x - 1
Thus, The value of the width of the rectangle is,
⇒ (x - 1)

THE SUM OF THREE CONSECUTIVE EVEN INTEGERS IS 72 FIND THE THIRD INTEGERS.
Answers
Answer: The three consecutive even numbers are 22, 24, 26
22+24+26 = 72
========================================================
Explanation:
x = first even numberx+2 = second even number directly right after x(x+2)+2 = x+4 = third even number directly after x+2For example, if x = 12, then we'd have x+2 = 12+2 = 14 and x+4 = 14+4 = 18.
However 12+14+18 = 44 is not 72 like we want.
You can guess-and-check your way to the answer, but a faster efficient route is to use algebra. Add up those x expressions and set the sum equal to 72 and solve.
(first) + (second) + (third) = 72
(x) + (x+2) + (x+4) = 72
3x+6 = 72
3x = 72-6
3x = 66
x = 66/3
x = 22
So we have,
x = 22 = first even numberx+2 = 22+2 = 24 = second even numberx+4 = 22+4 = 26 = third even numberAs a check: 22+24+26 = 72 which verifies the answers.

19). V = 381.51 cubic inches
20) The cylindrical box has a greater volume so Lin would prefer getting it.
Step-by-step explanation:
Assuming that the plastic bag filled with water was shaped like a sphere (bc there's not enough context to make it anything other than a sphere), the solution lies within an equation:
V = 4/3πr^3
This is the equation for finding the volume of sphere.
Hint: diameter = radius/2
V = 4/3π(4.5)^3
V = 4/3π(91.125)
V = 4.19(91.125)
V = 381.51 cubic inches
______________________________________________________
Equation of a rectangular prism: V = L * W * H
Equation of cylinder: V = πr^2h
Rectangle box:
V = 12 * 9 * 10
V = 120 * 9
V = 1080
Cylinder box:
V = π5^2(14)
V = π(25)(14)
V = 350 * 3.14
V = 1099

A 1,500-gallon tank contains 200 gallons of water. Water begins to run into the tank at the rate of 75 gallons
per hour. When will the tank be full but not overflowing?
Answers
Answer:
17hrs (a little more)
Step-by-step explanation:
The tank is 1500 gallon capacity, it already contains 200 gallons.
1500-200=1300
Now, you have to figure how many hrs it will take at 75 gallons / hr to reach the additional 1300 gallons.
1300÷75= 17.33
It says full, but not overflowing. So I would say around 17hrs

Answer:
C. Vertex: (1,-49); intercepts: x = 8,-6Step-by-step explanation:
x²-2x-48 = (x²-2x +1) - 1 - 48
= (x - 1)² - 49
Then
The vertex is (1 , - 49)
==================
x²-2x-48 = 0
⇔ (x - 1)² - 49 = 0
⇔ (x - 1)² = 49
⇔ x - 1 = 7 or x - 1 = -7
⇔ x = 8 or x = -6
Then
intercepts: x = 8,-6

The values for the highlighted variables that show how to subtract the rational expressions are; a = 6, x^2 + 6x is equal to x(x+6), and b=2.
What is rational expressions?From the information, the denominator and numerator of the first term are multiplied by x.
The difference of squares is factored as (a² -b²) = (a +b)(a -b), so the denominator of the first term can be factored.
The common factor x can be factored out of the denominator of the second term which gives ...
[tex]\dfrac{2}{x^2-36}-\dfrac{1}{x^2+6x}= \dfrac{2}{(x+6)(x-6)}-\dfrac{1}{x(x+6)}\quad a=6[/tex]
Now Multiplying the first term by x/x and the second term by (x-6)/(x-6) gives ...
[tex]\dfrac{2x}{(x+6)(x-6)x}-\dfrac{x-6}{(x+6)(x-6)x}\quad b=2,\ c=6[/tex]
Writing the sum over the common denominator, we have;
[tex]\dfrac{2x-x+6}{(x+6)(x-6)x}\quad d=2,\ e=6[/tex]
Collecting terms in the numerator gives ...
[tex]\dfrac{x+6}{(x+6)(x-6)x}\quad f=6[/tex]
Finally, canceling the common factor we get;
1/(x-6)x
The values of the letters are; a=6, b=2, c=6, d=2, e=6, f=6, g=1

The length of a rectangle is 10 cm and the width is 15 cm. What is the
area of the rectangle in square meters?
Answers
Answer:
0.015 m²
Step-by-step explanation:
Since we need the area in square meters, we need to first convert our centimeter values into meters.
[tex]\frac{1m}{100cm} =10cm[/tex]
1 · 10 = 10
10/100 = 0.1 m
[tex]\frac{1m}{100cm} =15cm[/tex]
1 · 15 = 15
15/100 = 0.15 m
The area of a rectangle is a = l · w. Plugging in the given values, we get:
a = 0.1 × 0.15
a = 0.015 m²
