Answer:

x=7

Step-by-step explanation:

-5*(x-4)-(-15)=0

(0 - 5 • (x - 4)) - -15 = 0

35 - 5x = -5 • (x - 7)

-5 • (x - 7) = 0

Solve : x-7 = 0

Add 7 to both sides of the equation :

x = 7

The points (1,2),(1,-3),and (5,-3) form a triangle on the coordinate plane. b. What is the perimeter of the triangle?

Alexeev081 [22]

The perimeter of the triangle is 13.56 units.

The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
