Answer:

Step-by-step explanation:

19² = 17² +x²

19² - 17² = x²

√361-289 =x

√72 = 8.5 ≈ x

Area = base*h/2 = 17*8.5/2 ≈ 72.3

Perimeter = 19+17+8.5= 44.5

and so on...

x²= 5² +13²...

A= 5*13/2 =...

P= 5+13+x=...

20² = 10² +x²...

A=10*x/2=...

P=20+10+x=...

x² = 5² +14²...

A=5*14/2 =...

P= 5+14+x = ...

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1
