Answer:
-8=2x-y get this into y=mx+b form to find the y-intercept
-y=-2x-8
y=2x+8
the y-intercept is 8 so it passes through (0,8)
to find the x-intercept, set y to equal zero
0=2x+8
-8=2x
x=-4
the x-intercept is -4 so it passes through (-4,0)
the slope is 2 based on the slope-intercept form
By definition the area of a rectangle is:
A = w * l
The perimeter is:
P = 2w + 2l
Where,
w: width
l: long
Substituting values:
300 = w * l
80 = 2w + 2l
Solving the system of equations we have:
l = 30 m
w = 10 m
Answer:
The length and width of the field are:
l = 30 m
w = 10 m
Answer:

V = 
V = 
V = 3591.4 cm³
Answer:
the width of a rectangular is 3 cm
Step-by-step explanation:
Length L = 10 cm
Perimeter P = 26 cm
Width W = ?
perimeter = 2L + 2W
26 = 2(10) + 2W
26 - 20 = 2W
6 = 2W
W = 6 / 2
W = 3 cm
therefore, the width of a rectangular is 3 cm
