Find the area of the shaded region
PIT_PIT [208]

Answer:

Area of the shaded region= 500inch^2

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle=\frac{1}{2}*Base*Height

           =\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

          = 30*10\\\\=300 inch^2

Area of the shaded region=  800-300= 500 inch^2

Suppose the sum of two integers is negative. Must both integers be negative? Explain.
mash [69]

Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.

Let me know if you'd  like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.
