18x^3-27x^2y
Answer:
(d.) [tex]18x^3-27x^2y[/tex]
Step-by-step explanation:
When given the following equation,
[tex](3x)^2(2x-3y)[/tex]
Systematically perform the operations. Use the order of operations, the order of operations states the following,
1. Parenthesis
2. Exponents/ radicals
3. Multiplication/ Division
4. Addition/ Subtraction
Remember, when performing an exponential operation, one multiplies the base by itself the number of times the exponent indicates. In the given equation, perform the exponent by multiplying the base (3x) by itself twice.
[tex](3x)^2(2x-3y)\\\\(3x)(3x)(2x-3y)\\\\(9x^2)(2x-3y)[/tex]
Now distribute, multiply every term inside the parenthesis by the term outside of it
[tex](9x^2)(2x-3y)\\\\(9x^2)(2x) + (9x^2)(-3y)\\[/tex]
Simplify,
[tex]18x^3-27x^2y[/tex]
Therefore the solution is (d.) [tex]18x^3-27x^2y[/tex]

answered: faith1993
Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
answered: evelynalper08
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7 2/3x + y = 7(2/3x + y = 7)32x + 3y = 21
Y= -2/3*x+7 | *3
3y= - 2x+21 | +2x
3y+2x=21 this is the correct answer
You multiply everything by 3 which equals 3y=2x+21 then you switch 21 and 3y which equals -21=2x-3y. Hope this helps

answered: Guest
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
\frac{2}{5}=\frac{x-18}{x}
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30

The perimeter of a rectangular wooden deck is 90 feet. The deck's length is 5 feet less than 4 times its width. Write a system of equations to represent this situation.
Answer:
width = w
length = 4w - 5
perimeter = 90 feet
substitute these values into the formula for perimeter of a rectangle
90ft = 2( w + 4w - 5)
90ft = 2( 5w - 5)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)

Multiple Select: Multiply and match each of the following
expressions.
A. (x − p) (x + p)
B. (x – 5) (x + 7)
C.(x + p) (x + p)
A.isz? - 2px – pº A.isx? – p2 B.isz? + 2x – 35
B.isx? - 20 – 35 Cisx2 + 2px +p?
Answer:
A. (x − p) (x + p) = x² - p²
B. (x – 5) (x + 7) = x² + 2x - 35
C. (x + p) (x + p) = x² + 2px + p²
Step-by-step explanation:
To find - Multiply and match each of the following expressions.
A. (x − p) (x + p)
B. (x – 5) (x + 7)
C.(x + p) (x + p)
Proof -
A.)
The expression is - (x − p) (x + p)
Now,
(x − p) (x + p) = x(x + p) - p(x + p)
= x(x) + x(p) - p(x) - p(p)
= x² + xp - px - p²
= x² - p²
⇒(x − p) (x + p) = x² - p²
B.)
The expression is - (x – 5) (x + 7)
Now,
(x − 5) (x + 7) = x(x + 7) - 5(x + 7)
= x(x) + x(7) - 5(x) - 5(7)
= x² + 7x - 5x - 35
= x² + 2x - 35
⇒(x − 5) (x + 7) = x² + 2x - 35
C.)
The expression is - (x + p) (x + p)
Now,
(x + p) (x + p) = x(x + p) + p(x + p)
= x(x) + x(p) + p(x) + p(p)
= x² + xp + px + p²
= x² + 2px + p²
⇒(x + p) (x + p) = x² + 2px + p²

What is the first step to finding the volume of the cylinder?
A.
Find the product of the diameter and the height.
B.
Use the diameter to find the area of the cylinder.
C.
Find the sum of the diameter and the height.
D.
Use the diameter to find the radius of the cylinder.
Answer:
D
Step-by-step explanation:
you find the radius by using the diameter
hence radius = diameter divide by 2 which is 1÷2 which is 0.5
next step the volume of the cylinder is πr^ 2h
22÷7 × 0.5×0.5×8 gives you 6.2857 to 5 significant number
The volume of the cylinder will be 6.28 square yards.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
The diameter of a cylinder is 1 yd.
The height is 8 yd.
Then the volume of the cylinder will be
Volume = (π / 4)d² h
Volume = (π / 4) x 1² x 8
Volume = (π / 4) x 8
Volume = 2π
Volume = 6.28 square yards

How many different triangles can you make if you are
given these three lengths for sides?
17 cm
13cm
23cm
Answer:
1 triangle can be formed
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.
