We can multiple this binomial and this trinomial to find an equivalent expression.

(x + 4)(3x^2 + 2x)

3x^3 + 2x^2 + 12x^2 + 8x

Combine like terms.

3x^3 + 14x^2 + 8x is the equivalent polynomial.

Kamila [148]

25% = 18

1% = 18 ÷ 25 = 0.72

100% = 0.72 x 100 = 72

Answer: (A) = 72

22/40 x 100% = 55%

Answer: (B) 55%

Find the sum of the convergent series 7 0.7 0.007

mafiozo [28]

$7+0.7+0.007+\cdots=7\left(1+\dfrac1{10}+\dfrac1{100}+\cdots\right)$

Let $S_n$ denote the $n$ th partial sum of the series, i.e.

$S_n=1+\dfrac1{10}+\dfrac1{100}+\cdots+\dfrac1{100^n}$

Then

$\dfrac1{10}S_n=\dfrac1{10}+\dfrac1{100}+\dfrac1{1000}+\dfrac1{10^{n+1}}$

and subtracting from $S_n$ we get

$S_n-\dfrac1{10}S_n=\dfrac9{10}S_n=1-\dfrac1{10^{n+1}}$
$\implies S_n=\dfrac{10}9\left(1-\dfrac1{10^{n+1}}\right)$

As $n\to\infty$ , the exponential term vanishes, leaving us with

$\displaystyle\lim_{n\to\infty}S_n=\dfrac{10}9$

and so

$7+0.7+0.007+\cdots=7.777\ldots=\dfrac{70}9$
