Answer:
[tex]x = 2, 4[/tex]
Step-by-step explanation:
Given :
[tex]\frac{4-x}{x^{2} -5x+4} + \frac{2}{x-1} =1[/tex]
=============================================================
Factorize the denominator of the first term :
⇒ x² - 5x + 4
⇒ x² - x - 4x + 4
⇒ x(x - 1) - 4(x - 1)
⇒ (x - 4)(x - 1)
============================================================
Hence, the equation now is :
[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2}{x-1} =1[/tex]
============================================================
Multiply the second term by (x - 4) in the numerator and denominator :
[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2(x-4)}{x-1(x-4)} =1[/tex]
============================================================
Combine the numerator of both terms and bring the denominator to the other side :
[tex]\frac{4-x+2(x-4)}{(x-1)(x-4)} = 1[/tex]
[tex]4 - x+2x-8 = x^{2} - 5x + 4[/tex]
[tex]x - 4 = x^{2} - 5x + 4[/tex]
[tex]x^{2} -5x-x+4+4=0[/tex]
[tex]x^{2} -6x+8=0[/tex]
[tex](x-4)(x-2)=0[/tex]
[tex]x = 2, 4[/tex]
Clint is interested in making an offer on a house with hardwood floors that will need to be replaced. The hallway is 18 feet by 6 feet. The kitchen is 20 feet by 30 feet. The living room is 25 feet by 45 feet. There are two bedrooms, which measure 12 feet by 16 feet each, plus a master bedroom that is 14 feet by 20 feet. If the cost of the flooring is $5.48 per square foot, and the cost of installation is $1.49 per square foot, how much can Clint plan to spend to replace the floors
The amount of money Clint will plan to spend to replace the floors is $17404.09
How to find the cost to replace the floor?The hardwood floor is rectangular.
Therefore,
area of hallway = 18 × 6 = 108 ft²
area of the kitchen = 20 × 30 = 600 ft²
area of the living room = 25 × 45 = 1125 ft²
area of each bedroom = 12 × 16 = 192 ft²
area of master bedroom = 14 × 20 = 280 ft²
Hence,
cost of flooring per square foot is $5.48
total cost for flooring = 108(5.48) + 600(5.48) + 1125(5.48) + 192(5.48) + 192(5.48) + 280(5.48) = $13683.56
Cost of installation is $1.49 per square.
total cost of installation = 108(1.49) + 600(1.49) + 1125(1.49) + 192(1.49) + 192(1.49) + 280(1.49) = $3720.53
Total amount to replace the floor = 13683.56 + 3720.53 = $17404.09

How to determine the area of AOB?The triangle AOB is an equilateral triangle with the following parameters:
Side length, x = 6
Angle, y = 60
The area of the triangle is then calculated using:
Area = 0.5 * x^2 * sin(y)
So, we have:
Area = 0.5 * 6^2 * sin(60)

Can someone please help me with my Question #29 of The Quadratic Relations for me please?
Answer:
Calculate the first differences between the y-values:
[tex]\sf 3 \underset{+1}{\longrightarrow} 4 \underset{+3}{\longrightarrow} 7 \underset{+5}{\longrightarrow} 12 \underset{+7}{\longrightarrow} 19[/tex]
As the first differences are not the same, we need to calculate the second differences:
[tex]\sf 1 \underset{+2}{\longrightarrow} 3 \underset{+2}{\longrightarrow} 5 \underset{+2}{\longrightarrow} 7[/tex]
As the second differences are the same, the relationship between the variable is quadratic and will contain an [tex]x^2[/tex] term.
--------------------------------------------------------------------------------------------------
To determine the quadratic equation
The coefficient of [tex]x^2[/tex] is always half of the second difference.
As the second difference is 2, and half of 2 is 1, the coefficient of [tex]x^2[/tex] is 1.
The standard form of a quadratic equation is: [tex]y=ax^2+bx+c[/tex]
(where a, b and c are constants to be found).
We have already determined that the coefficient of [tex]x^2[/tex] is 1.
Therefore, a = 1
From the given table, when [tex]x=0[/tex], [tex]y=12[/tex].
[tex]\implies a(0)^2+b(0)+c=12[/tex]
[tex]\implies c=12[/tex]
Finally, to find b, substitute the found values of a and c into the equation, then substitute one of the ordered pairs from the given table:
[tex]\begin{aligned}\implies x^2+bx+12 & = y\\ \textsf{at }(1,19) \implies (1)^2+b(1)+12 & = 19\\ 1+b+12 & = 19\\b+13 & =19\\b&=6\end{aligned}[/tex]
Therefore, the quadratic equation for the given ordered pairs is:
[tex]y=x^2+6x+12[/tex]

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. find the remainder of (h4 h2 – 2) ÷ (h 3). the remainder is .
The remainder of (h4 h2 – 2) ÷ (h 3). The remainder is 88.
RemainderGiven:
(h⁴ + h² – 2) ÷ (h + 3)
Using reminder theorem
First step is to equate:
h + 3 =0
h = - 3
Second step is to determine the remainder
Substitute h = - 3 into (h⁴ + h² – 2)
Hence:
h⁴ + h² – 2 = (-3)⁴ + (-3)² - 2
h⁴ + h² – 2= 81 + 9 - 2

triangle ABC has perimeter 22cm
AB=8cm
BC=5cm
by calculation deduce whether triangle ABC is a right-angled triangle
Answer:
the triangle is not right-angled
Step-by-step explanation:
First of all, we are told that the perimeter of the triangle is 22 and the two sides are given, 8cm and 5cm respectively. This means that the third side is: 22-(8+5) = 9cm
From this as see that 9cm is the highest length we have and if it were a right-angled triangle, this could be the hypotenuse. Now, to be sure of the initial response we use the Pythagoras theorem. We know that the hypotenuse² = adjacent² + opposite²
let's use the measurements we are given in the question
8²+5²=AC²
64+25=89
AC=√89
AC=9.433981132
AC =9.43cm
and when we add 8+5+9.43 to calculate the perimeter we get 22.43 which is not the initial perimeter, this the triangle isn't right-angled

The surface area of the cylinder is 1155.52 square ft if the radius and height of the cylinder are 8 ft and 15 ft.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
The surface area of the cylinder:
[tex]\rm A =2\pi rh+2\pi r^2[/tex]
r = 8 ft

Janelle babysat for 6 hours at an hourly rate. After she got paid she spent $12 at Walmart. She came home with $36. How much money did she make per hour?
Please explain with steps :)
Answer:
$8/hour
Step-by-step explanation:
We will start by finding how much money she made before spending it. The amount of money she took home added to how much money she spent will give us this. ([tex]12 + 36 = 48[/tex]). This means she made $48 before spending it.
Now we can solve for her wage. Let [tex]x[/tex] be her hourly wage
(the 6 is the number of hours she worked, this multiplied by her wage should give us 48)
[tex]6x = 48\\x = 8[/tex]

24/4 = 4x/4
6 = x
Both equations are equal to x = 6, therefore they are equivalent
Answer:
Yes
