What is the area of a triangle with vertices at (-2,1), (2,1), and (3,4)

The area of a triangle is determined by the formula: Base x Height * 1/2

You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.

4 - 1 = 3

So the height is 3.

Base = 4

Height = 3

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
