Manny needs to solve the equation x2 – 8x – 24 = 0 by completing the square. Which pair of steps is the most efficient way to begin?
Answer:
B
Step-by-step explanation:
So for some reason the person didn't put the equations... I had the same question so here they are.
A.x^2 – 8x = 24
x2 – 8x + 4 = 24 + 4
B.x^2 – 8x = 24
x2 – 8x + 16 = 24 + 16
C.x^2 – 8x = 24
x2 – 8x + 64 = 24 + 64
D.x^2 – 8x = 24
x2 – 8x + 144 = 24 + 144

The quadratic equation can be solved by completing square method. The steps to solve the given equation are explained in detail.
What is a quadratic equation?The general form of a quadratic equation is given as ax^2 + bx + c = 0.
Here, a ≠ 0 and b and c are integers.
The degree of a quadratic equation is 2.
The given equation is,
x^2 - 8x -24 = 0
To solve this equation by completing square method, it has to be transformed into the form of (a + b)^2.
The steps for this method are given as follows,
(i) Find the coefficient of x^2. The square root of the this coefficient is the value of a.
(ii) Find the term containing non-square part. In the given case it is -8x.
(iii) Compare the coefficient of this term with 2ab. it gives,
2ab = -8
=> 2 × 1 × b = -8
=> b = -4
(iv) Write the equation in the form of a^2 + 2ab + b^2 leaving the remaining term as it is. For the given equation it can be written as,
x^2 - 8x + 4^2 - 40 = 0
=> x^2 - 8x + 4^2 = 40
(v) Now, write the equation in terms of (a +b)^2 and get the solution. In this case it is written as,
(x - 4)^2 = 40
=> x - 4 = ±√40
=> x = 4 ±√40

5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350
Answer:
b. PHP 31,250.00
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = PHP 25,000
Rate = 2.5%
Time = 10 years
Simple interest = principal × rate × time
= PHP 25,000 × 2.5% × 10
= 25,000 × 0.025 × 10
= 6,250
Simple interest = PHP 6,250
Investment after 10 years = principal + simple interest
= PHP 25,000 + PHP 6,250
= PHP 31,250
Investment after 10 years = PHP 31,250

The cylinder has a height of 30 cm and a radius of 11 cm. Work out the total surface area of
the cylinder. Give your answer correct to 2 significant figures.
Answer:
[tex]A=2833.71\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of the cylinder, h = 30 cm
The radius of the cylinder, r = 11 cm
We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :
[tex]A=2\pi rh+2\pi r^2\\\\A=2\pi \times 11\times 30+2\pi \times (11)^2\\\\A=2833.71\ cm^2[/tex]
So, the total surface area of the cylinder is [tex]2833.71\ cm^2[/tex].

The equivalent value of the expressions are solved by the exponents
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
A = 25ˣ
On simplifying , we get
A = ( 5 . 5 )ˣ
A = ( 25 )ˣ
And , A = 5ˣ . 5ˣ
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
A = 5²ˣ
A = 25ˣ
Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ

Step-by-step explanation:
Option 2 is already simplified to 20x + 30y
Option 4,
10*2x=20x and 10*3y= 30y so option 4 also simplifies to 20x + 30y

Which best represents an equation to solve for x?
3x = 75
3x +75 = 90
3x + 75 + 90 = 180
3x + 75 +90 = 360
Answer:
3x + 75 + 90 = 180
x = 5°
Step-by-step explanation:
3x + 75° + 90° = 180°( being sum of angles of triangle)
3x = 180° - 75°- 90°
3x = 15°
x = 15° / 3
x = 5°

Solution :
We have to find the largest fraction in each group.
a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]
[tex]$\frac{5}{6}$[/tex] → when we divide the number 5 with 6, we get 0.833
[tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805
Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.
b). [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]
[tex]$\frac{5}{12}$[/tex] → when we divide the number 5 with 12, we get 0.416
[tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375
Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.
c). [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]
[tex]$\frac{2}{5}$[/tex] → when we divide the number 2 with 5, we get 0.40
[tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42
Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.
d). [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and [tex]$\frac{19}{21}$[/tex]
[tex]$\frac{5}{7}$[/tex] → when we divide the number 5 with 7, we get 0.714
[tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928
[tex]$\frac{19}{21}$[/tex] → when we divide 19 by 21, we get the value 0.904
Therefore, in this group, [tex]$\frac{13}{14}$[/tex] is the largest fraction.
