The perimeter of the triangle below is 8x - 6.
1 answer:
Answer:
QR = 4x - 6
Step-by-step explanation:
A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.
From the question:
Perimeter of triangle PQR = PQ + PR + QR
But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.
Therefore substituting gives:
8x - 6 = (x + 1) + (3x - 1) + QR
8x - 6 = (x + 3x + 1 - 1) + QR
8x - 6 = 4x + QR
QR = (8x - 6) - 4x
QR = 4x - 6

Answer:
Step-by-step explanation:
Here we are given two coordinates through which our lines passes through. Now we are going to use the two point form to find the equation of the line.
The two point form is given as
Here we are given two coordinates . Thus replacing them in the formula and simplifying it will give us the equation of the line.
subtracting y and adding 8 on both sides we get
Hence this is our equation of the line passing through (5,3) & (4,1)
