1.
Step E)
The mistake is:
2x - 5 on the numeratorCorrect way is:
3 - (2x - 8) = 3 - 2x + 8 = 11 - 2x2.
Step C)
The mistake is:
5x = x² + 4Correct way is:
5x = (x+2)²5x = x² + 4x + 4Answer:
First picture the step E is incorrect because:
[tex]\frac{3}{(x+4)(x-4)} -\frac{2x-8}{(x+4)(x-4)}[/tex][tex]=\frac{-2x-5}{(x+4)(x-4)}[/tex]
Instead you should change the step E to be: [tex]\frac{-2x-5}{(x+4)(x-4)}[/tex]
Second picture the step C is incorrect because:
[tex](\sqrt{5x})^{2}[/tex] =[tex](x+2)^{2}[/tex]
[tex]5x = x^{2} +4x+4[/tex]
[tex]not[/tex] [tex]5x=x^{2} +4[/tex]
Instead you should change the step C to be: [tex]5x = x^{2} +4x+4[/tex]
Change step D to:
[tex]5x -x^{2} -4x -4=0[/tex]
Change step E to:
[tex]x^{2}-x+4=0[/tex]
Change step F to:
[tex]x=\frac{1+-\sqrt{1-16} }{2}[/tex]

For every pound a company spends on advertising, it spends £0.45 on its website. Express the amount spent on advertising to the amount spent on its website as a ratio in its simplest form
Step-by-step explanation:
COMPANY HAS EARNED (IF) = 1 POUND
SPENDS ON WEBSITE = 0.45 POUND
THEN RATIO = 1-0.45÷ 0.45
= 0.55/0.45

Maisie bought a house.
The value of the house decreased by 10% in 2016.
For three consecutive years, 2017, 2018 and 2019 the value of the house
increased.
Each year the percentage increase in value was the same each time.
The value of the house at the end of 2019 was 55.52% more than he paid for
the house.
Calculate the percentage increase in value of the house for each of the three
consecutive years.
The percentage increase in the value of the house each of the three years is 11.49%.
What is the percentage increase in the value of the house?The equation that can be used to represent the percentage change in the value of the house is:
(100x - 10%) + 3x% = 55.52%
90% + 3x = 55.52%
90% - 55.52% = 3x
34,48% = 3x
x = 34.48/3
x = 11.49%

Find the value of x that makes each parallelogram the given type (answer both please)
Answer:
a. x = 12
b. x = 4
Step-by-step explanation:
a. RECTANGLE
ABCD is a rectangle, AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
10x + 8 = 9x + 20
10x - 9x = 20 - 8
x = 12
b. RHOMBUS
Diagonal of a rectangle bisect opposite angles.
Therefore,
(5x + 3)° = (2x + 15)°
5x + 3 = 2x + 15
5x - 2x = 15 - 3
3x = 12
x = 12/3
x = 4
The value of x for a rectangle will be 12.
The value of X for a rhombus is 4.
What is a parallelogram?A basic quadrilateral containing two sets of side lengths is known as a parallelogram. There are four types of parallelograms each with diffrent kinds of properties.
a. RECTANGLE
ABCD is a rectangle, Therfore the diagonals that are made will also be equal.
AC = BD
[tex]10x +8 = 9x + 20\\10x - 9x = 20 - 8[/tex]
x = 12
b. RHOMBUS
As this is a rhombus that is presented, the angle which is divided with the help of the diagonal will both be equal.
5x + 3 = 2x + 15
5x - 2x = 15 - 3
Simplifying the equation,
3x = 12
x = 12/3
x = 4

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve an equation to find the original length of each side of the equilateral triangle.
Answer:
The original length of each side of the equilateral triangle = x =15 inches
Step-by-step explanation:
Let Original length of side of equilateral triangle = x
If it is increased by 5 inches, the length will become = x+5
Since in equilateral triangle all the ides have same length so,
New Length of side 1 = x+5
New of side 2 = x+5
New Length of side 3 = x+5
Perimeter of triangle = 60 inches
We need to find the value of x
The formula used is: [tex]Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3[/tex]
Putting values in formula and finding x
[tex]Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15[/tex]
So, the original length of each side of the equilateral triangle = x =15 inches

Identify the coordinates of the vertices of each figure after the similarity transformation.
Answer:
After translation:
Translation: (x, y) → (x-6, y-8)
W'X'Y'Z' = W'(-10, 0), X'(-10, -8), Y'(-18, -4), Z'(-14, 8)
After dilation:
Dilation: (x, y) → (2x, 2y), centered at (0, 0)
W''X''Y''Z'' = W'' (-20, 0), X'' (-8, 0) , Y'' (-24, 8), Z'' (-16, 32)
Step-by-step explanation:
Given the vertices of the Quadrilateral WXYZ
W(-4, 8)X(-4, 0)Y(-12, 4)Z(-8, 16)As the rule of translation is given by
Translation: (x, y) → (x-6, y-8)
So, after the translation the vertices of Quadrilateral WXYZ will be translated as:
W(-4, 8) → (x-6, y-8) ⇒ (-4-6, 8-8) = W'(-10, 0)
X(-4, 0) → (x-6, y-8) ⇒ (-4-6, 0-8) = X'(-10, -8)
Y(-12, 4) → (x-6, y-8) ⇒ (-12-6, 4-8) = Y'(-18, -4)
Z(-8, 16) → (x-6, y-8) ⇒ (-8-6, 16-8) = Z'(-14, 8)
Therefore,
W'X'Y'Z' = W'(-10, 0), X'(-10, -8), Y'(-18, -4), Z'(-14, 8)
Next, the rule of dilation is given by
Dilation: (x, y) → (2x, 2y), centered at (0, 0)
W'(-10, 0) → (2x, 2y) ⇒ (2(-10), 2(0)) = W'' (-20, 0)
X'(-4, 0) → (2x, 2y) ⇒ (2(-4), 2(0)) = X'' (-8, 0)
Y'(-12, 4) → (2x, 2y) ⇒ (2(-12), 2(4)) = Y'' (-24, 8)
Z'(-8, 16) → (2x, 2y) ⇒ (2(-8), 2(16)) = Z'' (-16, 32)
Therefore,
W''X''Y''Z'' = W'' (-20, 0), X'' (-8, 0) , Y'' (-24, 8), Z'' (-16, 32)

Gerald inherited $35,000 from his uncle. He spends $1400 a month. After how many months
will Gerald have less than $2,000?
Answer:
18 months
Step-by-step explanation:
35,000÷18=1944
First, we need to figure out the amounts of months that Gerald has total, with all of the money. So, we divide 35000 by 1400, this leaves us with 25. So, if he keeps spending 1400 per month, it will last him 25 months, but this is not what the question asks, is it? In 25 months, his inheritance will be fully depleted, in 24 months he will have spent 33,600 dollars, meaning he will have 1400 dollars left (35000 - (24 * 1400))and in 23 months, he will have spent 32,200 dollars, meaning that he will have 2800 dollars.
"In 24 months he will have spent 33,600 dollars, meaning he will have 1400 dollars left 35000 - (24 * 1400)"
35000 - (24 * 1400)
