Your friend asks you to him with his dog grooming business and will pay you 4 pennies for the first job. you agree to if he quadruples your payment for each job completed. after 2 grooming jobs, you will receive 16 pennies, and after 3 grooming jobs, you will receive 64 pennies. complete and solve the equation that finds the number of pennies he will pay you after the 9th dog grooming job.

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

hope this if needed hmu
