Let 
x---------> the length side of rectangle
y---------> the width side of rectangle

we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2

28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m

the answer is
the length side of rectangle is 240 m
 the width side of rectangle is 120 m

Write the standard form of the line that passes through the given points (6,1) and (5,4)
Serggg [28]

The standard form:

Ax+By=C

The point-slope form:

y-y_1=m(x-x_1)

m - slope

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (6, 1) and (5, 4). Substitute:

m=\dfrac{4-1}{5-6}=\dfrac{3}{-1}=-3

y-1=-3(x-1)      <em>use distributive property</em>

y-1=-3x+3          <em>add 1 to both sides</em>

y=-3x+4         <em>add 3x to both sides</em>

\boxed{3x+y=4}
