Need help !!!Divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78.

lana [24]

Hello,

Maybe i have not understood "into".

$\dfrac{25a^4+19a^2-a-78}{5a^2+6a-9} =5a^2-6a+20+ \dfrac{-175a+102}{5a^2+6a-9}$

Square NOPQ is dilated by a scale factor of to form square N'O'P'Q'. Side N'O' measures 4. What is the measure of side NO?

KIM [24]

$\begin{gathered} \text{NOPQ was dilated to N'O'P'Q'} \\ \text{The scale factor is }\frac{2}{3} \\ N^{\prime}O^{\prime}=4 \\ N^{\prime}O^{\prime}=\frac{2}{3}NO \\ 4=\frac{2}{3}NO \\ \text{cross multiply} \\ 12=2NO \\ NO=\frac{12}{2} \\ NO=6 \end{gathered}$

PLEASE HELP Simplify (a^6)*(a^8)*(a^n)

Varvara68 [4.7K]

Answer:

$a^{14+n}$

Step-by-step explanation:

You add the exponents when the number/variable is the same, so:

6+8+n= 14+n

So:

$a^{14+n}$

a television normally sells for $499 what is now discounted 25%. The sales tax rate is 6.5%. What is the total cost of televisio

matrenka [14]

Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?

well, if we take 499 to be the 100, how much is 25%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
499&100\\
d&25
\end{array}\implies \cfrac{499}{d}=\cfrac{100}{25} \cfrac{499\cdot 25}{100}=d
\\\\\\
124.75=d\qquad \textit{so the new price is }499-124.75\implies 374.25$

now, applying the sales tax to the discounted price.

if we take 374.25 to be the 100%, how much is 6.5%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
374.25&100\\ t&6.5
\end{array}\implies \cfrac{374.25}{t}=\cfrac{100}{6.5}\implies \cfrac{374.25\cdot 6.5}{100}=t$

so, the total cost will then be 374.25 + t.
