Answer:
I'm just assuming here ok so I'm sorry if I'm wrong but I think it took them 12hrs
To do this, you must use the order of operations.
3·2=6
6+4=10
Now to solve (-)x.
Since -x comes in front of 4, you must make your equation:
-x+10
Nothing is written for x, so now, you have the answer.
-x+10
Perimeter is the sum of all outside dimensions:
5 + 3 + 1 + 2 + 4 + 5 = 20cm
Area = (5 x 5) - (2*1) = 25 - 2 = 23 cm^2
Yes this is the correct answer. The slope field shown is the differential equation dy/dx = x+y
All points along the line x+y = k, for some constant k, will have the same tangent slope k. For example, the line x+y = 0 will have every point with tangent slope 0 for the solution y(x). It may not be 100% clear, but this graph has horizontal tickmarks on the line x+y = 0, or the tickmarks are close to being horizontal. Using geogebra, I checked the others and they produced completely different graphs, which allowed me to rule them out.
