Answer:
width=11/2
length=8
Step-by-step explanation:
44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>
44=2w^2 - 3w <em>distribute</em>
2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>
(w+4)(2w-11) <em>factor</em>
width=11/2
(11/2 x 2) - 3
length = 8
Step-by-step explanation:
let the speed of diesel train = x
the equation would be:
(2+6)x = 6(x+15)
8x = 6x+90
8x-6x = 90
2x = 90
x = 90/2
x = 45
Therefore, the speed of diesel train =
45 mph
Answer:
The lines are parallel to each other.
To figure this out you need to use the formula: m = y2 - y1 / x2 - x1
m represents the slope of the line.
So for the first line:
m = 4 - 2 ÷ -5 - (-9)
m = 2 / 4
Simplify: m = 1 / 2
The slope of the first line is 1 / 2.
For the second line:
m = 6 - 4 ÷ 1 - (-3)
m = 2 / 4
Simplify: m = 1 / 2
So, you can see that the slopes of both lines are the same. When the slopes are the same, that means that the lines are parallel to each other. When the coordinates are the same, that means that the lines are the same. When the slopes are flipped to each other and have are the opposite sign (positive or negative), then the lines are perpendicular.
