Which expression is equivalent to 2(x2 – 1) + 3x(x – 4)?
(1) 5x2 – 5
(3) 5x2 – 12x – 1
(2) 5x2 - 6
(4) 5x2 – 12x – 2
The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
How to find equivalent expression?
The equivalent expression of the expression can be found as follows;
2(x² – 1) + 3x(x – 4)
open the brackets
2x² - 2 + 3x² - 12x
Therefore, let's combine like terms
2x² + 3x² - 12x - 2
Let's do the arithmetic for like terms
2x² + 3x² - 12x - 2
5x² - 12x - 2
Therefore, the equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

Answer:
here, suppose the missing length be X
hy ^2 = (one side square )^2 +(Other side square)^2
29^2= X^2 + 21^2
841 = X^2 + 441
X^2 = 841 - 441
X^2 = 400
X = 20 .........taking square root both side
the value is missing side length is 20 .
A ball falls vertically after being dropped.
The ball falls a distance dmetres in a time of t seconds.
dis directly proportional to the square of t.
The ball fals 20 metres in a time of 2 seconds.
(a) Find a formula for din terms of t.
Answer:
d = 5t^2
Step-by-step explanation:
"d is directly proportional to the square of t"
d = kt^2
To find k use
"The ball falls 20 metres in a time of 2 seconds."
20 = k(2^2)
20 = k(4)
Divide both sides by 4
5 = k
Using k = 5 the formula becomes
d = 5t^2
Mia took 20 seconds to run 100m. Find the ratio of distance traveled to the time Emma took to run 100m.
Answer:
The ratio should be 100 : 20. If it needs to be simplified then 5:1
Step-by-step explanation:
100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1
(If it doesn't need to be simplified then 100 : 20)

2) In both Eudidean and spherical geometry, a triangle can have two right angles.
3) In both Euclidean and spherical geometry, through any point not on a given line there is a line
parallel to the given line.
4) In spherical geometry, some quadrilaterals are parallelograms.
5) In spherical geometry, any two given lines must intersect.
6) None of these are true.
4) In spherical geometry, some quadrilaterals are parallelograms.
In spherical geometry, some quadrilaterals are parallelograms is a true statement. Thus option D is correct.
What is spherical geometry?Instead of the sort of geometries studied in trigonometry or solid geometry, the research of shapes on a structure's surface. White lines are large rounds in spherical, therefore any three layers intersect at two locations.
A spherical quadrilateral is a bounded surface that is homomorphic to a compact disk. It has four distinct local maxima called extremities, a Riemannian measurement that has constant curvature 1 everywhere else, aside from the corners, and or the demarcation arcs between it intersections. a dome shape. the collection of rectangular shapes with specified angles.
Therefore, option D is the correct option.

Patty made a banner that has an area of 112 square inches. The length and width of the banner are whole numbers. The length is 7 times greater than the width. What are the dimensions of the banner?
Answer:
The width of the banner is 4 inch and the length of the banner is 28 inch
Step-by-step explanation:
Given
Length is seven times its width
Let the width be "X", then length would be 7X
The banner is of rectangular shape.
Its area is 112 square inches
[tex]X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4[/tex]
Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch

What is the distance between two points with coordinates (12,0) and (0,35)
Answer:
caca I I I ii I I I I I I I I I I I I I I I.
Answer:
37
Step-by-step explanation:
-use the distance formula
d²= (x2-x1)²+(y2-y1)² where d is the distance and x1 =12, x2=0, and y1=0, y2=35
d² = (0-12)² + (35-0) ²
d² = (-12)² + 35² = 144+ 1225 = 1369
d =√1369 = 37

Comprei 15 rolos para uma instalação elétrica gastei 3/8 de 1 rolo quantos trabalhos eu posso realizar com o material comprado?
Responder:
40 instalações
Explicação passo a passo:
Rolos totais de instalações adquiridas = 15
Rolos usados por instalação = 3/8 de um rolo
O número de instalações que os 15 rolos podem durar pode ser calculado assim:
1 instalação = 3/8 rolo
x instalações = 15 rolos
Multiplicação cruzada
3/8 x = 15
x = 15 ÷ 3/8
x = 15 * 8/3
x = 5 * 8
x = 40

-7x - 2y = 14
6x + 6y = 18
Answer:
x=-4, y=7
Step-by-step explanation:
Answers : x = (15/6), y =
(1/2).
Step-by-step explanation:
Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.

Model the problem situation with a linear inequality.
Answer:
this is easy. you just need to write and equation that shows how many pounds of each fruit you can buy in total (x for 1 pound of grapes and y for 1 pound of watermelon). this would make the equation 32 = 4x + 2x.
