Which are sums of perfect cubes? Check all that apply. 8x6 27 x9 1 81x3 16x6 x6 x3 27x9 x12 9x3 27x9.

Black_prince [1.1K]

The equations which are sums of perfect cubes are as follows;

$\rm 8x^6+27x^9+1$

$\rm x^6+x^3$

$\rm 27x^9+x^{12}$

<h3>Perfect cubes;</h3>

Perfect cubes are the numbers that are the triple product of the same number.

We have to determine

Which are sums of perfect cubes?

1. The given equation is $\rm 8x^6+27x^9+1$ .

The equation can be written as;

$\rm 8x^6+27x^9+1\\\\2^3(x^2)^3+3^3(x^3)^3+1^3$

All the terms in the expression are can be represented as perfect cubes.

2. The given equation is $\rm 81x^3+16x^6$ .

The equation can be written as;

$\rm 81x^3+16x^6\\\\9^2x^3+4^2(x^2)3$

In this, all the terms are not perfect cubes, some of them are squares.

3. The given equation is $\rm x^6+x^3$ .

The equation can be written as;

$\rm x^6+x^3\\\\(x^2)^3+x^3$

All the terms in the expression are perfect cubes.

4. The given equation is $\rm 27x^9+x^{12}$ .

The equation can be written as;

$\rm 27x^9+x^{12}\\\\3^3(x^3)^3+(x^4)^3$

All the terms in the expression are perfect cubes.

5. The given equation is $\rm 9x^3+27x^9$ .

The equation can be written as;

$\rm 9x^3+27x^9\\\\3^2x^3+3^3(x^3)^3$

In this, all the terms are not perfect cubes, some of them are squares too.

What is the solutions of the equation 2 (x+2) ^2-4=28

JulsSmile [24]

Answer:

x = 2 x = -6

Step-by-step explanation:

2 (x+2) ^2-4=28

Add 4 to each side

2 (x+2) ^2-4+4=28+4

2 (x+2) ^2= 32

Divide by 2

2/2 (x+2) ^2=32/2

(x+2)^2 = 16

Take the square root of each side

sqrt((x+2)^2) =±sqrt( 16)

x+2 = ±4

Subtract 2 from each side

x+2-2 = -2±4

x = -2±4

x = -2+4 and x = -2-4

x = 2 x = -6

Frank deposits 5350.00 in a savings account. The account pays an annual Interest rate of 1%. Ile makes no other deposits or with

9966 [12]

Answer:

If the account paid a <u>monthly</u> interest instead of <u>annual</u>, the answer would be $162.12

Step-by-step explanation:

<h3>PS: THIS ISN'T THE ANSWER TO THIS QUESTION BECAUSE IT STATED 'ANNUAL INTEREST' BUT I USED MONTHLY INTEREST INSTEAD. HOPE THIS HELPS SOMEONE ELSE THOUGH.</h3><h3><u>FIRST MONTH</u></h3>

Original value is $5350.00

Percentage increase(interest gained) is 1%

Total value after 1st month is equal to the Original Value + The interest

<em>$5350.00 x 0.01 </em>(0.01 = 1/100 = 1%) =<em> $53.50</em>

Do not try and do this altogether as you will get the answer wrong. Instead calculate month by month.

At the end of the <u>first month</u>, he has <em>($5350.00 + $53.50) = $5403.50</em>

<h3><u>SECOND MONTH</u></h3>

Original Value is $5403.50

Percentage increase(interest gained) is <em>still </em>1%

Total value after the 2nd month is equal to the Original Value+The interest

<em>$5403.50 x 0.01 = $54.035</em>

<u>ALWAYS</u> round off to the nearest cent before continuing.

At the end of the <u>second month</u>, he has <em>($5403.50 + $54.04) = $5457.54</em>

<h3><u>THIRD MONTH</u></h3>

Original Value is $5457.54

Percentage increase(interest gained) is 1%

Total value after the 3rd month is equal to the Original Value + The interest

<em>$5457.54 x 0.01 = $54.5754 = $54.58</em>

When rounding off, if the number is 5 or higher, add 1 to the digit before it.

At the end of the <u>third month</u>, he has <em>($5457.54 + $54.58) = $5512.12</em>

The question asks, how much interest did his money earn. If you calculated like how I did above, picking the interest should be easy.

Simply add, the first month's interest, to the second month's interest, to the third month's interest.

<em>$53.50 + $54.04 + $54.58 = $162.12</em>
