The width is 2 and the length is 9 because 9 times 2 is 18 and 2 times 5 is 10. 10 minus 1 is 9 which then again 9 times 2 is 18 which is the area.
Answer:
because you add. if you would subtract 6 inches by 3 inches it would be 3 inches.
To find the slope we will need to differentiate!
Step 1:

// let's take the derivative with respect to x
Since there is no x value specified there is an infinite number of slope values that we can input into this equation.
We have two points on a plane p1(150, 25000), p2(90, 19000) and we can find a linear equation from them, lets calculate the slope:
m = (y2 - y1)/(x2 - x1)
where x1, y1 and x2, y2 are the point's coordinates:
m = (19000 - 25000)/(90 - 150)
m = -6000/-60
m = 100
so we have the slope now, and we can use the equation of the line for a point and having the slope, that equation is:
y - y1 = m(x - x1)
so we substitute:
y - 25000 = 100(x - 150)
y = 100x + 25000 - 15000
y = 100x + 10000
so this is the linear equation that models the airplane descent, when the airplane hits the ground, then y = 0, and we need to find the x, that is the position in relation to the runway:
<span>0 = 100x + 10000
</span>-100x = 10000
x = -100
32 = 2m - 6
32 + 6 = 2m
38 = 2m
m = 19
