The expression (2w - 2)³ × (8w⁶) is equivalent to :
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
(2w - 2)³ × (8w⁶)
The given expression is -
(2w - 2)³ × (8w⁶)
{2(w - 2)}³ × (8w⁶)
8(w - 1)³ × (8w⁶)
(a+b)³ = a³ - 3a²b + 3ab² - b³
So, on expanding, we will get -
8(w³ - 1 - 3w² + 3w) x (8w⁶)
(8w³ - 8 - 24w² + 24w )(8w⁶)
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷
Therefore, the expression (2w - 2)³ × (8w⁶) is equivalent to :
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

5x +2y=-9
3x+4y= -11
por el método de igualacion porfavor hacerlo en folio y me mandáis una foto si no no entiendo
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
Answer:
x = −1 and y = −2

Step-by-step explanation:
A coin collection contains d dimes and q quarters worth a total of $50.
Which equation models this information?
d + q = 50
10d + 25q = 50
0.1d + 0.25q = 50
0.01d + 0.25q = 50
Answer:
0.1d + 0.25q = 50
Step-by-step explanation:
dimes are worth 10 cents so it's 0.1 and d represents the unknown amount
quarters are worth 25 cents so it's 0.25 and q represents the unknown amount

How do I simplify this complex rational expression?
Answer:
[tex]\frac{23x+3}{20(x+1)}[/tex]
Step-by-step explanation:
Separate the fractions into a more readable format.
Factorise the denominators of all the fractions where possible. For [tex]x^2-1[/tex] apply DOTS ==> Difference of two squares*
Simplify the fractions.
I wrote out my working so I hope that helps :>>
*Difference of two squares is a method of factorising the sum of two squares, where one of them is negative. [tex]a^2-b^2 = (a-b)(a+b)[/tex]

the path of a toy rocket is modelled by the equation y=-x^2+6x+2, where x is the horizontal distance, in metres, travelled and y is the height, in metres, of the toy rocket above the ground. what is the maximum height of the toy rocket? at what horizontal distance does the maximum height occur?
Answer:
The path of a toy rocket is defined by the relation y=-3x^2+11x+4, where x is the horizontal distance, in meters, traveled and y is the height, in metres, above the ground.
Determine the zeros of the relation.
-3x^2 + 11x + 4 = 0
---
3x^2 - 11x -4 = 0
Factor:
3x^2 - 12x + x - 4 = 0
---
3x(x-4) + x-4 = 0
---
(x-4)(3x+1) = 0
---
x = 4 or x = -1/3
============================
f(x) = -3x^2+11x+4
How far has the rocket traveled horizontally when it lands on the ground?
4 ft.
==================
What is the maximum height of the rocket above the ground, to the nearest hundredth of a meter?
---
max occurs when x = -b/2a = -11/(2*-3) = 11/6
height = f(11/6) = 14.083 ft
In a basketball game Elena scored twice as many points as Tyler Tyler scores four points fewer than Noah and Noah scores three points as Mai of Mai scores 5 points how many points did Elena score
Full question:
In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning
Answer and explanation:
We start from known to unknown. We know that Mai scored 5 points and so we work from here.
Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points
Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points
Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points
