I’m not sure if your asking for the solution, but Hope this helps!
Answer:

Since the measurement can't be negative the correct answer for this case would be 
Step-by-step explanation:
Let's assume that the figure attached illustrate the situation.
For this case the we know that the original area given by:

And we know that the initial area is a half of the entire area in red
, so then:

And we know that the area for a rectangular pieces is the length multiplied by the width so we have this:

We multiply both terms using algebra and the distributive property and we got:

And we can rewrite the expression like this:

And we can solve this using the quadratic formula given by:

Where
if we replace we got:

And the two possible solutions are then:

Since the measurement can't be negative the correct answer for this case would be 
Answer:
The slope would be C) -1/2
Step-by-step explanation:
To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -4)/(0 - 2)
m = 1/-2
m = -1/2
U.S customary system also known as the English system.
Founded by the British, but they dropped it. Now only three countries in the world still use this system.
