: Kenneth measured a hotel and made a scale drawing. The scale he used was 1 inch =4 feet. The actual length of a room in the ho
natulia [17]

The room is 5 inches long in the drawing.

Step-by-step explanation:

Given,

Scale drawing used by Kenneth;

1 inch = 4 feet

Ratio of scale = 1:4

Actual length of room = 20 feet

Let,

x be the length in drawing

Ratio of actual length = x:20

Using proportion

Scale ratio :: Actual ratio

1:4::x:20

Product of mean = Product of extreme

4*x=20*1\\4x=20

Dividing both sides by 4

\frac{4x}{4}=\frac{20}{4}\\x=5

The room is 5 inches long in the drawing.

Divide using synthetic division, and write a summary statement in fraction form. 2x^4-x^3-15x^2+3x/x+3
aev [14]
So... first off, we sort the dividend, the numerator, in descending order... so, looking at the exponents in this one, is already sorted in descending order, from 4 down to 1, so that's done.

then the divisor, we have x+3, that means x + 3 = 0, x = -3,
so, we'll be using -3 for the synthetic division then.

\bf \cfrac{2x^4-x^3-15x^2+3x}{x+3}\\\\
-------------------------------\\\\

\begin{array}{r|rrrrrrrrrl}
-3&&2&-1&-15&3\\
&&&-6&21&-18\\
--&&-&--&--&--\\
&&2&-7&6&\boxed{-15}&\leftarrow remainder
\end{array}

and now, we'll use those coefficients, dropping the exponents of the polynomial by one, and the remainder, remains as a fraction with the divisior of x+3.

\bf 2x^3-7x^2+6x-\frac{15}{x+3}
