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

x+6=5(y+6)\\x+6=5y+30

Plugging x = 7y, we get

7y+6=5y+30\\2y=24\\y=12

Hence, from equation (1)

x = 7(12)

x =84

In 6 years, Harry will be of 12 + 6 =18 years.

X = Harry's Age

Nick's age is 7x 

In 6 years Harry is 7x+6, and Nick is 5(x+6)

7x+6=5x+30

2x+6=30

2x = 24

x = 12

Harry = 12 years old and in 6 years Harry will be 18.

Use a commutative property to complete the statement. mn=
n200080 [17]
The commutative property of multiplication states that u can " commute " the numbers, move them around, and the result will still be the same.
Example : 2 * 4 = 4 * 2

Therefore, mn = nm

Find the perimeter of the polygon. Round your answer to the nearest tenth.
dimulka [17.4K]

The perimeter of the polygon is 26.1 units.

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 (x_{1} ,y_{1} ) , (x_{2} ,y_{2} )  is given by

\sqrt{(x_{2} -x_{1} )^{2}+(y_{2} -y_{1} )^{2}  }

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=\sqrt{(4 -2 )^{2}+(5 -0 )^{2}  }=\sqrt{4+25} =\sqrt{29}=5.38 units

RS=\sqrt{(8 -4 )^{2}+(7 -5 )^{2}  }=\sqrt{16+4} =\sqrt{20}=4.47 units

ST=\sqrt{(6 -8 )^{2}+(4 -7)^{2}  }=\sqrt{4+9} =\sqrt{13}=3.60 units

TU=\sqrt{(10 -6 )^{2}+(3 -4 )^{2}  }=\sqrt{16+1} =\sqrt{17}=4.12 units

QU=\sqrt{(10 -2 )^{2}+(3 -0 )^{2}  }=\sqrt{64+9} =\sqrt{73}=8.54 units

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.
