Answer:
10x
Step-by-step explanation:
<h3>Expression:</h3>
Length = x unit
Width = 4*x = 4x
Perimeter = 2*(length + width )
= 2*(x + 4x)
= 2 *5x
= 10x
Answer:
7x - 3y = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x + 7y = 15 into this form
Subtract 3x from both sides
7y = - 3x + 15 ( divide all terms by 7 )
y = -
x +
← in slope- intercept form
with slope m = - 
Given a line with slope m the the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation of the line
To find c substitute (4, 9) into the partial equation
9 =
+ c ⇒ c - 
y =
x -
← in slope- intercept form
Multiply through by 3
3y = 7x - 1 ( subtract 3y from both sides )
0 = 7x - 3y - 1 ( add 1 to both sides )
1 = 7x - 3y, that is
7x - 3y = 1 ← in standard form
I am pretty sure that this is it
