Answer:
14 ft
Step-by-step explanation:
Given:
- Bedroom is 4 ft longer than it is wide.
- Area is 252 ft².
Let x = width of the bedroom:
- width = x ft
- length = (x + 4) ft
Therefore:
To find the value(s) of x, complete the square.
Add the square of half the coefficient of the term in x to both sides:
<u>Factor</u> the perfect trinomial on the left side:
<u>Square root</u> both sides:
Therefore:
As width cannot be negative, the width of the room is 14 ft.
Answer:
its the third one because it has a lot of electrons on it already
Answer:
y=5x+4
Step-by-step explanation:
ANSWER
The required line is BC
EXPLANATION
We want to find the line that passes through
and has slope
Since the x-value of the given point is zero, the point
is the y-intercept.
From the above graph, the two lines that contains
are line CE and line BC.
Since, the slope
is negative, line BC is the required line because it is sloping backwards.
We can confirm this by using the point,
and
to find the slope and obtain
For the given graph , slope of the line is equal to ( 1 / 2 ).
As given in the question,
Form the given graph,
Scale is given by,
On x-axis each unit of the graph represent 1 unit.
On y- axis each unit of the graph represent 1 unit.
Consider two coordinates from the line of the graph,
( x₁ , y₁ ) = ( 1, 2 )
( x₂ , y₂ ) = ( 3, 3 )
Slope of the line = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substitute the value in the formula of the slope we get,
Slope of the line = ( 3 - 2 ) / ( 3 - 1 )
⇒ Slope of the line = 1 / 2
Therefore, for the given graph , slope of the line is equal to ( 1 / 2 ).
