This is a sum of cubes:

<em>x</em>⁶ - 27<em>y</em>³ = (<em>x</em>²)³ + (-3<em>y</em>)³

Recall that

<em>a</em>³ + <em>b</em>³ = (<em>a</em> + <em>b</em>) (<em>a</em>² - <em>ab</em> + <em>b</em>²)

So we have

<em>x</em>⁶ - 27<em>y</em>³ = (<em>x</em>² - 3<em>y</em>) ((<em>x</em>²)² - <em>x</em>² (-3<em>y</em>) + (-3<em>y</em>)²)

<em>x</em>⁶ - 27<em>y</em>³ = (<em>x</em>² - 3<em>y</em>) (<em>x</em>⁴ + 3<em>x</em>²<em>y</em> + 9<em>y</em>²)

In the equation, 6(3x+5) -4x =35 , what are some of the steps that should be taken to solve for x? Select all that apply.
Natalija [7]
You need to combine like terms and subtract 30. How you find the answer is you work the problem first 1. Distribute the 6 (18x+30)-4x=35 then 2. combine like terms 18x and -4x. (14x+30)=35 then 3. Subtract 30 from both sides (14x)=5

Answer:

y = 3x + 3

Step-by-step explanation:

when you check, only that equation delivers the correct x and y pairs.

x = 0, => y = 3×0 + 3 = 3

x = 1, y = 3×1 + 3 = 3+3 = 6

x = 2, y = 3×2 + 3 = 6 + 3 = 9

x = 3, y = 3×3 + 3 = 9 + 3 = 12

it all fits.

In a circle H with m angle GKJ=27 find the m angle GHJ
abruzzese [7]

In a circle H with a measure of angle ∠GKJ = 27°. Then the measure of angle ∠GHJ will be 54°

<h3>What is a circle?</h3>

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

In a circle H with a measure of angle ∠GKJ = 27°.

Then the measure of angle ∠GHJ will be

We know that a chord's slope in the centre is double that of the chord's slope at the perimeter.

Then we have

∠GHJ = 2 x ∠GKJ

∠GHJ = 2 x 27°

∠GHJ = 54°
