Answer:

$\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}$

Step-by-step explanation:

Given

$\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}$

Required

Fill in the gaps

Going by the given parameters, we have that

$\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}$

$x^2 - 9x + 8$ , when factorized is $(x-1)(x-8)$

Hence; the expression becomes

$\frac{4x+2}{(x-1)(x-8)} = \frac{A}{(x-8)(x-1)} + \frac{B}{(x-1)(x-8)}$

Combine Fractions

$\frac{4x+2}{(x-1)(x-8)} = \frac{A + B}{(x-8)(x-1)}$

Simplify the denominators

$4x + 2 = A + B$

By direct comparison

$A = 4x$

$B = 2$

Hence, the complete expression is

$\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}$

Samson opened a bank account with 1.25% simple interest. The total amount of interest Samson will earn after 20 years is $812.50

IRINA_888 [86]

Step-by-step explanation:

The principal amount recieves a simple interest every year. The simple interest rate is given as $1.25\%$ .

It is given that the total amount after 20 years is $812.50

$Total=Principal+Interest\textrm{ = }P+P\times i\times T$

Here $P$ is the principal amount, $i$ is the interest rate, $T$ is the time period.

$812.50=P+P\times (1.25\times \frac{1}{100})\times 20yr=P\times 1.25\\P=650\$$

∴ Samson had $650 when he opened the account.
