Step-by-step explanation:
just multiply the 2 together to get the area
it would just be
[tex](5x) \times (2{x}^{2} - 4x + 13)[/tex]
use the distributive property
[tex]10 {x}^{3} - 20 {x}^{2} + 65[/tex]
unless you want to simplify the answer, this would be the answer
simplified, it would be
[tex]5(2{x}^{3} - 4 {x}^{2} + 13)[/tex]

Work Shown:
3 blue
3+4+5 = 12 total
3/12 = 1/4 = 0.25
Answer: As a fraction it would be 333/ 1,332 and as a decimal it would be 0.25.
Step-by-step explanation:
1. you add all of the marbles and then you would get 1,332
2. there are 333 blue marbles, so it would be 333/1,332
3. if you want it in decimal form it will be 0.25 if you round that to the nearst tenth it would be 0.3.
4. if you want it in fraction form it will be 333/1,332
I hope this is right. Good luck !.if x-2y=10 and y is three times the value of x, what is the value of x-y ?
Answer:
3x = y
x - 2(3x) = 10
x- 6x = 10
-5x = 10
x = -2
3x = y
3(-2) = y
y = -6
x is -2 and y is -6.
The center of a hyperbola is located at the origin. one focus is located at (0, 20), and its associated directrix is represented by the line y = . what is the equation of the hyperbola? = 1 = 1 = 1 = 1
The equation of the hyperbola is D. [tex]y^2/16^2-x^2/12^2=1[/tex]
Calculations and Parameters:Given that the focus is at (0, 20)
Directrix is y= -256/20
What is the relation between a, b, and c?
[tex]a^2 +b^2 = c^2\\b^2 + (16)^2= (20)^2\\b^2= 400 -256\\b^2= 144[/tex]
b= 12

Answer:
0.0238 meter per pieces
Step-by-step explanation:
(1/6)/7=0.0238
For confirmation:-
0.0238*7=0.1666=1/6
Answer:
0.02381m
Step-by-step explanation:
1/6 of a meter is 16.667 cm.
16.667 divided by 7 = 2.381cm
To check: 2.381 x 7 = 16.667 (correct)
2.381 cm in meters is 0.02381 m.
The answer is 0.02381m.

Stuart bought a sweater on sale for 30% discount off the original price and another 25% off the discounted price . If the original price of the sweater was 600 , what was the final price of a sweater?.
Answer:
$301.50
Step-by-step explanation:
Given that:
Stuart brought a sweater on sale for 30% discount off.
Another 25% discount off
Original price = 600
To Find:
What was the final price of a sweater?
Solve:
$600 x 30% = $180
$600 - $180 = $402 (discounted price after 30% off)
$402 x 25% = $100.50
$402-100.50 = $301.50 (discounted price after 25% off & the final price)
Hence, the final price is $301.50

Blake gives piano lessons in the evenings. He earns $20 for each piano lesson and has between 0 and 6 lessons each evening. The amount he earns in an evening depends on the number of lessons he gives. What is the range of this relation?
Answer:
The correct answer is B. {0, 20, 40, 60, 80, 100, 120}
Step-by-step explanation:
1. Let's check all the information given to answer this question correctly:
Rate of each piano lesson Blake gives = US$ 20
Blake can give between 0 and 6 lessons every evening
Earnings = Number of lessons * Rate of each lesson
2. What is the range of this relation?
Let's recall that the domain of a relation is the set of all values for which the relation is defined, and the range of the relation is the set of all values that the relation takes.
It means that the domain of the relation in this case is the number of lessons that Blake can give every evening:
{0, 1, 2, 3, 4, 5, 6}
And the range of this relation is the amount Blake earns in an evening depending on the number of lessons he gives:
{0, 20, 40, 60, 80, 100, 120}
The correct answer is B. {0, 20, 40, 60, 80, 100, 120}
If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream, What

What number is represented by P
The number that is represented by P is 0.0057
Narrow it down.The point P is between 5 * 10^-3 and and 6*10^-3When you go to the bottom line, P is on the 7th division from the left.Going from left to right increases PP is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.One of the answers is 5.7 * 10^-3The other answer is .0057I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.If it is not correct, then 5.7 * 10^-3 is the answer.
IDΚ, help, what's the value of x,
8x-2=-9+7x
Answer:
x = -7
Step-by-step explanation:
8x - 2 = -9 +7x
in this type of problem you have to get all the X's together on one side, and all the common variables together on the other.
8x = -7 + 7x (you add 2 to boths sides. The -2 and 2 clear out on the left side. The 2 and -9 added together forms -7 on the right)
x = -7 (you subtract 7x from both sides. The 7x and -7x cancel out on the right and you are left with on 1 x on the left side)
Answer:
x = -7Step-by-step explanation:
In this question we have given an equation that is 8x - 2 = -9 + 7x . And we're aksed to find the value of x .
Solution : -
[tex] \longmapsto \qquad \: 8x - 2 = -9 + 7x[/tex]
Step 1 : Adding 2 to both sides :
[tex] \longmapsto \qquad \:8x - \cancel{ 2} + \cancel{ 2} = - 9 + 7x+2[/tex]
On further calculations, we get :
[tex] \longmapsto \qquad \:8x =7x - 7[/tex]
Step 2 : Subtracting 7x on both sides :
[tex] \longmapsto \qquad \:8x - 7x = \cancel{7x} - 7 - \cancel{7x}[/tex]
On further calculations, we get :
[tex] \longmapsto \qquad \: \red{\underline{\boxed{ \frak{x = - 7}}}}[/tex]
Henceforth , value of x is - 7 .Verifying : -
Now ww are verifying our answer by substituting value of x in given equation . So ,
8x - 2 = -9 + 7x8 ( -7 ) - 2 = -9 + 7 ( -7 )-56 - 2 = -9 - 49-58 = -58L.H.S = R.H.SHence, Verified.Therefore, our answer is correct .
