{(2x^{3}  + 3x^{2} )}^{7}
EXPANDED: VERY LONG

128x^{21} +1344x^{18} y^{2} +6048x^{15} y^{4} +15120x^{12} y^{6} +22680x^{9} y^{8} +20412x^{6} y^{10} +10206x^{3} y^{12} +2187y^{14}

I used the Binomial Theorem, Which States
(a + b)(a + b)= {a}^{2} + 2ab  + {b}^{2}   \\
({a}^{2} + 2ab  + {b}^{2} )(a + b)={a}^{3} + 3 {a}^{2} b   + 3a {b}^{2} + {b}^{3}
({a}^{3} + 3 {a}^{2} b   + 3a {b}^{2} + {b}^{3}) \times (a + b) = i \: believe \: you \: get \: the \: pattern \: now

Lauren pays $19.99 for a membership fee to an online music store. Lauren buys songs from a new album at the price of $0.99 each.
sdas [7]

The right answer is Option B.

Step-by-step explanation:

Let,

Number of songs = x

Price of 1 song = $0.99

Membership fee = $19.99

Total amount paid = $21.97

According to given statement;

0.99x+19.99=21.97

Subtracting 19.99 from both sides

0.99x+19.99-19.99=21.97-19.99\\0.99x=1.98

Dividing both sides by 0.99

\frac{0.99x}{0.99}=\frac{1.98}{0.99}\\x=2

Lauren bought 2 songs.

The right answer is Option B.

solve for y
y-4=x+8
add 4 to both sides
y=x+12

If r(x) = 3x – 1 and s(x) = 2x 1, which expression is equivalent to (startfraction r over s endfraction) (6)? startfraction 3 (6
viva [34]

The expression which is equivalent to the given ratio of the two provided binary fraction is startfraction 3 (6) minus 1 over 2 (6) 1 endfraction.

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given binary functions are.

r(x) = 3x - 1

s(x) = 2x +1

The expression which has to be found out is,

\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{3(6)-1}{2(6)+1}\right)\\\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{18-1}{12+1}\right)\\\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{17}{13}\right)

Thus, the expression which is equivalent to the given ratio of the two provided binary fraction is startfraction 3 (6) minus 1 over 2 (6) 1 endfraction.
