Answer:
8/12
Step-by-step explanation:
find common denominator then add
5/12 + 3/12 = 8/12 or 2/3 as simplify
Part A

To graph this, we plot open holes at -2 and 3 on the number line. Shade between these open holes to represent values between -2 and 3, but we don't include the endpoints.
See figure 1 below.
===============================================
Part B
Solve the first inequality to get

Now solve the second inequality

We have 
The graph will have an open hole at -3 and a closed/filled in circle at 1. We shade everywhere but the region between these marked values. The left portion in blue represents stuff smaller than -3; the right portion in red represents values equal to 1 or larger.
See figure 2 below.
It would be A because you have add them to find the y number
The area of a shape is the amount of space it can occupy.
<em>The number of isosceles triangle in the grid is: </em>
<em />
The dimension of the grid is given as:

Calculate the area


The area of each isosceles triangle is given as:

The number (n) of the triangle in an x-by-x grid is:

So, we have:

Express as products


Hence, the number of isosceles triangle in the grid is:
