Answer:

\hookrightarrow \sf  x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096

solving steps:

\rightarrow \sf (x + 4)^6

\bold{rewrite \ the \ following}

\rightarrow \sf (x + 4)^2   (x + 4)^2   (x + 4)^2

\bold {formula \ used : \sf  (x+a)^2 = (x^2 + 2xa + a^2)}

\rightarrow \sf (x^2 + 8x+16)    (x^2 + 8x+16)    (x^2 + 8x+16)

\bold{simplify \ by  \ removing \ parenthesis}

\rightarrow \sf (x^4 +8x^3 + 16x^2 + 8x^3 +64x^2 + 128x+16x^2+128x+256 ) (x^2 + 8x+16)

\bold{basic \ addition \ of \ integers }

\rightarrow \sf (x^4+16x^3+96x^2+256x+256) (x^2 + 8x+16)

\bold{remove \ parenthesis}

\rightarrow \sf (x^6 + 16x^5 + 96x^4 + 256x^3 + 256x^2 + 8x^6 + 128x^4 + 768x^3 + 2048x^2 + 2048 + 16x^4 + 256x^3 + 1536x^2 + 4096x + 4096)

\bold {final \ answer:}

\rightarrow \sf  x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096

Write an algebraic expression for 12 less than a number times 7
forsale [732]

Answer: 7*N - 12

Step-by-step explanation:

Let's break this so is easier to interpret.

"12 less than a number"

if we call the number as N, this is written as:

N - 12

and the complete sentence is:

"12 less than a number times 7"

So we must multiply our number, N, by 7.

Then the expression is:

7*N - 12

Answer:

$776.96

Step-by-step explanation:

The computation of the average daily balance for August is shown below:

Particulars              Days         Days end balance   Total balance

                                                                                    for the period

                              (A)                   (B)                        (A × B)

Aug 1 to Aug 9         9            $728.15                     $6,533.35

Aug 10 to Aug 14     5            $864.15                     $4,321.70

                                      ($728.15 + $136.19)

Aug 15 to Aug 22    8           $572.34                     $4,578.72

                                     ($864.15 - $136.19)

Aug 23 to Aug 31    9           $959.12                      $8,632.08

                                    ($572.34 + $386.78)

Total                       31                                              $24,085.85

Now the average daily balance is

= $24,085.85 ÷ 31 days

= $776.96
