Step-by-step explanation:
Hey there!
Given;
[tex] = (x - 4)( {x}^{2} + 2x - 5)[/tex]
[tex] = x( {x}^{2} + 2x - 5) - 4( {x}^{2} + 2x - 5)[/tex]
[tex] = {x}^{3} + 2 {x}^{2} - 5x - 4 {x}^{2} - 8x + 20[/tex]
[tex] = {x}^{3} - 2 {x}^{2} - 13x + 20[/tex]
Therefore, Option D is correct answer.
Q.no.
Given;
[tex] =( 4 {x}^{3} + 9xy + 8y) - (3 {x}^{3} + 5xy - 8y)[/tex]
[tex] = 4 {x}^{3} + 9xy + 8y - 3 {x}^{3} - 5xy + 8y[/tex]
[tex] = {x}^{3} + 4xy + 16y[/tex]
Therefore, answer is Option D.
Qno.
Given;
[tex]5 {x}^{2} + 29x + 20 = 0[/tex]
[tex]5 {x}^{2} + (25 + 4)x + 20 = 0[/tex]
[tex]5 {x}^{2} + 25x + 4x + 20 = 0[/tex]
[tex]5x(x + 5) + 4(x + 5) = 0[/tex]
(5x + 4)(x + 5) =0
Either (5x+4)= 0,
5x = -4
X = -4/5
Or, X+5 = 0
X = -5.
Therefore, X= -5, -4/5.
Hope it helps....

It is categorical data.
- What is your biggest source of stress?
We can have different answers which can not be categorized into groups.
It is not categorical data.
- How has your job impacted your personal life?
Everyone will have different answers so it is not categorical data.
- In the past week, how many hours of overtime did you work?

If f(x) = 3x - 1 and g(x) = x + 2, find (f- g)(x).
I can’t find it
Answer:
[tex](f-g)(x)=2x-3[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=3x-1\text{ and } g(x)=x+2[/tex]
And we want to find:
[tex](f-g)(x)[/tex]
This is equivalent to:
[tex]=f(x)-g(x)[/tex]
By substitution:
[tex]=(3x-1)-(x+2)[/tex]
Simplify. Distribute:
[tex]=(3x-1)+(-x-2)[/tex]
Rearrange:
[tex]=(3x-x)+(-1-2)[/tex]
Therefore:
[tex](f-g)(x)=2x-3[/tex]

Circle geometry please help,
Answer:
7. Inscribed angle
Step-by-step explanation:
7. Inscribed angle
8.
y° = 70°
z° = 140°
8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.
Therefore, y° = 70°
Measure of central angle is two times the measure of the inscribed angle.
Therefore,
z° = 2* 70° = 140°

in the figure, AC=20cm CD=22cm and AE=16cm find the length of BD.
Answer:
17.6 cm
Step-by-step explanation:
Area of triangle equals to half of the base times height, i.e. A = 1/2 × b × h.
1/2 x 22 x 16 = 1/2 x 20 x BD
BD = (1/2 x 22 x 16) / (1/2 x 20)
