Nick is now seven times as old as harry. In 6 years , nick will be five times as old as harry. How old will harry be in 6 years?
2 answers:
Answer:
18 years
Step-by-step explanation:
Let Nick age is x years and Harry's age is y years.
Hence, we have the equation
x = 7y ......(1)
After six years, Nick's age is (x+6) and Harry's age is (y+6)
Hence, we have
Plugging x = 7y, we get
Hence, from equation (1)
x = 7(12)
x =84
In 6 years, Harry will be of 12 + 6 =18 years.

To find the perimeter of the polygon.
<h3>What is polygon?</h3>A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
Given that:
Distance between points ,
is given by
As per the graph,
point Q is (2,0)
point R is (4,5)
point S is (8,7)
point T is (6,4)
point U is (10,3)
QR=
RS=
ST=
TU=
QU=
Perimeter refers to sum of lengths of all the sides.
Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units
So. the perimeter of the polygon is 26.1 units.
