Answer:

n = -5.4

Step-by-step explanation:

−7.24 + 4.8n − 4.77 = −0.67 + 6.9n

Subtract 4.77 from −7.24 to get −12.01.

-12.01 + 4.8n = -0.67 + 6.9n

Subtract 6.9n from both sides

-12.01 + 4.8n - 6.9n = 0.67

Combine 4.8n and −6.9n to get −2.1n

-12.01 = 2.1n = -0.67

Add 12.01 to both sides.

-2.1n = -0.67 + 12.01

Add −0.67 and 12.01 to get 11.34.

−2.1n = 11.34

Divide both sides by −2.1.

n = \frac{1134}{-210}

Reduce the Fraction \frac{1134}{-210}  to lowest terms by extracting and canceling out 42.

n = -\frac{27}{5} = -5\frac{2}{5} = -5.4

Find the perimeter of the polygon with the vertices X(−1, 3), Y(3, 0), and Z(−1,−2). Round your answer to the nearest hundredth
antoniya [11.8K]

Answer:

The perimeter of the polygon is P=14.47\ units

Step-by-step explanation:

we know that

The perimeter is the sum of the length sides of the polygon

In this problem

P=XY+YZ+XZ

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

step 1

Find the distance XY

we have

X(−1, 3), Y(3, 0)

substitute

d=\sqrt{(0-3)^{2}+(3+1)^{2}}

d=\sqrt{25}

dXY=5\ units

step 2

Find the distance YZ

we have

Y(3, 0), Z(−1,−2)

substitute

d=\sqrt{(-2-0)^{2}+(-1-3)^{2}}

d=\sqrt{20}

dYZ=4.47\ units

step 3

Find the distance XZ

we have

X(−1, 3), Z(−1,−2)

substitute

d=\sqrt{(-2-3)^{2}+(-1+1)^{2}}

d=\sqrt{25}

dXZ=5\ units

step 4

Find the perimeter

P=XY+YZ+XZ

P=5+4.47+5=14.47\ units
