Answer:

area of the kitchen

Step-by-step explanation:

in real life the dimensions are 10*40=400 cm=4 m and 18*40=720 cm=7.2 m

Area of the bedroom is A=4*7.2=28.8  m^2

Area of the kitchen  is  300.000 cm^2=30 m^2

30>28.8

The bigger area is  area of the kitchen

Answer:

300,000 cm^{2} is bigger

Step-by-step explanation:

10 x 40 = 400

18 x 40 = 720

400 x 720 = 288,000 cm^{2} (area of the bedroom)

300,000 cm^{2} is bigger by 12,000 cm^{2} (so the kitchen is bigger)

Solve x^2 +14x=15 by completing the square
ivanzaharov [21]

Answer:

x = -15 and x = 1

Step-by-step explanation:

Since we have to use the complete the square method, we first need to <u>rewrite the equation</u> in the form x^{2}+2ax+a^{2}=(x+a)^{2}.

This results in x^{2} + 14x + 7^{2} = 15 + 7^{2}.

Next, we <u>simplify the equation</u> to get x^{2} +14x+7^{2} = 64.

<u>Factoring </u>the left side gives us (x+7)^{2} = 64.

Finally we <u>solve the equations</u>: x+7=\sqrt{64} and x+7=-\sqrt{64}.

This gives us  x=1, and x=-15

You deposit $500 in an account that pays 8% annual interest compounded yearly. What is the account balance after six years? Form
Diano4ka-milaya [45]
Principal, P = $500
r =8% = 0.08, the interest rate
n = 1, the compounding interval
t = 6 years

The value after 6 years is
A = P(1 +  \frac{r}{n} )^{nt}
That is,
A = $500*(1 + 0.08)⁶ = $793.44

Answer: $793.44

Use the matrix tool to solve the system of equations. Enter the answer as an
BARSIC [14]

Answer:

x=\frac{1}{4}

y=-2

Step-by-step explanation:

Given:

8x + y = 0

4x-y=3

Convert your equation into matrices form

\begin{bmatrix}8&1&0\\4&-1&3\end{bmatrix}

Solve using reduced row reduction (RREF)

\begin{bmatrix}8&1&0\\4&-1&3\end{bmatrix}

\begin{bmatrix}8&1&0\\8&-2&6\end{bmatrix}

\begin{bmatrix}8&1&0\\0&-3&6\end{bmatrix}

\begin{bmatrix}8&1&0\\0&-1&2\end{bmatrix}

\begin{bmatrix}8&0&2\\0&-1&2\end{bmatrix}

\begin{bmatrix}1&0&\frac{2}{8}\\0&1&-2\end{bmatrix}

\begin{bmatrix}1&0&\frac{1}{4}\\0&1&-2\end{bmatrix}

x=\frac{1}{4}

y=-2
