The sum of the quotients of 25x^2/5x and the quotient of 8x^2/x is ?
const2013 [10]
If you would like to solve (25 * x^2) / (5 * x) + (8 * x^2) / x.
it would be easy  calculate this using the following steps:

(25 * x^2) / (5 * x) + (8 * x^2<span>) / x = 5 * x + 8 * x = 13 * x
</span>
<span>The correct answer would be 13 * x.</span>

Answer:

The sequence of transformations that maps ΔABC to ΔA'B'C' is the reflection across the <u>line y = x</u> and a translation <u>10 units right and 4 units up</u>, equivalent to T₍₁₀, ₄₎

Step-by-step explanation:

For a reflection across the line y = -x, we have, (x, y) → (y, x)

Therefore, the point of the preimage A(-6, 2) before the reflection, becomes the point A''(2, -6) after the reflection across the line y = -x

The translation from the point A''(2, -6) to the point A'(12, -2) is T(10, 4)

Given that rotation and translation transformations are rigid transformations, the transformations that maps point A to A' will also map points B and C to points B' and C'

Therefore, a sequence of transformation maps ΔABC to ΔA'B'C'. The sequence of transformations that maps ΔABC to ΔA'B'C' is the reflection across the line y = x and a translation 10 units right and 4 units up, which is T₍₁₀, ₄₎

Find the missing terms of the arithmetic sequence ...,27,?,?,?,53,... Show each step of the process clearly
Alja [10]

Answer:

Step-by-step explanation:

Looking at the arithmetic sequence, the 4th term is 27 the 8th term is 53. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

Therefore, the 4th term, T4 will be

27 = a + (4 - 1) d

27 = a + 3d - - - - - - - - 1

The 8th term, t8 would be

53 = a +(8 - 1) d

53 = a + 7d - - - - - - - - -2

Subtracting equation 1 from equation 2, it becomes

- 26 = - 4d

d = - 26/- 4 = 6.5

Substituting d = 6.5 into equation 1, it becomes

53 = a + 7 × 6.5

53 = a + 45.5

a = 53 - 45.5 = 7.5

The missing terms are

7.5, 14, 20.5, 27, 33.5, 40, 46.5, 53

X<br> (2x - 7)^3= (2x)^3- 7^3<br> = 8x3 - 343
emmainna [20.7K]

Answer:

(2x - 7)³ ≠ (2x)³- 7³

Step-by-step explanation:

(2x - 7)³= (2x)³- 7³

Use pascal's triangle to expand left side. Simplify all else.

(2x)³ + 3(2x)²(-7)¹ + 3(2x)¹(-7)² + (-7)³ = 8x³- 343

8x³ + 3(4x²)(-7) + 3(2x)(49) + (-7)³ = 8x³- 343

8x³ - 84x² + 294x - 343 = 8x³- 343

The radius of a cylindrical gift box is ​(4xplus1​) inches. The height of the gift box is three times the radius. What is the su
denis23 [38]

Answer:

(5x+1)\pi

Step-by-step explanation:

Given:

The radius of a cylindrical gift box = 4x+1

The height of the gift box is three times the radius.

Question asked:

What is the surface area of the​ cylinder ?

Solution:

The height of the gift box is three times the radius means,

height = 3(4x+1)

          = 3\times4x+3\times1\\= 12x+3

Now, surface area of the​ cylinder = 2\pi r(r+h)

                                                        =2\pi[4x+1](4x+1+12x+3)\\=8\pi x+2\pi(16x+4)\\=8\pi x+32\pi x+8\pi\\=40\pi x+8\pi\\=8\pi(5x+1) \ Taking \ common

Therefore, surface area of the​ cylinder is (5x+1)\pi.
