Alan drew a scale drawing of a house and its lot. The scale he used was 1 millimeter: 5 meters. In the drawing, the lawn in the

50 meters

Explanation

you can easily solve this by using a rule of three.

Step 1

Let

$\begin{gathered} 1\text{ milemeter}\rightarrow5\text{ meters} \\ \text{the proportion is} \\ \frac{1\text{ mm}}{5\text{ mt}} \end{gathered}$

x represents the length of the actual lawn

then

$\begin{gathered} 10\text{ mm}\rightarrow x\text{ mt} \\ \text{the proportion is} \\ \frac{10\text{ mm}}{\text{xmt}} \end{gathered}$

the proportion is the same, so

Step 2

$\begin{gathered} \frac{1}{5}=\frac{10}{x} \\ \text{solve for x} \\ 1\cdot x=5\cdot10 \\ x=50 \end{gathered}$

so, the length is 50 meters

What is the answer for 2n^2-8n=-9 ?

lbvjy [14]

2n^2-8n=9

divide by 2

2(n^2-4n) =9

add (4/2)^2 =4 to each side completing the square

(n^2-4n+4 ) =9/2+4

(n-2)^2 = 9/2+8/2

(n-2)^2 =17/2

take the square root of each side

n-2 = +-sqrt(17/2)

add 2 to each side

n = 2+- sqrt (17/2)

Answer:2+ sqrt (17/2),2- sqrt (17/2)
