ANSWER
EXPLANATION
We use the method of completing the squares.
The equation is
We rewrite the above equation to obtain;
We divide through by 3 to obtain;
We add half the coefficient of
to both sides of the equation to get,
The right hand side is now a perfect square.
We now take square root of both sides to get;
We add -2 to both sides,
We simplify to obtain,

Answer: Distance between O and the line 1 is 3 inches.
Explanation:
Since we have given that
Distance between point A and the line 1 = 10 inches
Distance between point B and the line 1 = 4 inches
Total length of segment AB is given by
Since O is midpoint of the line segment AB.
so, AO is given by
Now, Distance between O and the line 1 is given by
Hence, Distance between O and the line 1 is 3 inches.
Answer:
The length of the field on the drawing is 55 cm.
Step-by-step explanation:
Given:
Mark made a scale drawing of a soccer field.
Using a scale of .5 cm=1 m.
The actual length of the field is 110 m.
Now, to find the length of the field on drawing.
Let the length of the field on drawing be
As given 0.5 cm is equivalent to 1 m.
Thus, is equivalent to 110 m.
Now, to get the length of the field on drawing by using cross multiplication method:
<em>By cross multiplying we get:</em>
⇒
⇒
Therefore, the length of the field on the drawing is 55 cm.
