Answer
Find out the perimeter of the isosceles triangle.
To prove
As shown in the figure.
P(0,4) , Q(-2,0) and R(2,0) are the vertices of the triangle PQR.
Formula

As P(0,4) and Q(-2,0)


In the isoceles triangle the two sides of the triangles are equal .
Therefore PQ = PR

As Q(-2,0) and R(2,0)


QR = 16 unit


Answer:
A
Step-by-step explanation:
The slop formula is
and in the first one the rise increase per y (x) is 2 units and the run (y) is 1 as we calculated the run as how many units x rises per y and A is the answer due to it being the one which follows the rule.
Answer:
20
Step-by-step explanation:
The lower quartile Q₁ is the value at the left side of the box, that is
Q₁ = 20
So you would use GEMDAS or PEMDAS
-8-1+4x2
-8-1+8
