Answer:

14.4222

Step-by-step explanation:

Distance between two points = √(x₂ – x₁)² + (y₂ – y₁)²

Distance between two points = √(6 – -2)² + (-5 – 7)²

√(6 – -2)² + (-5 – 7)²

√8² + (-12)²

√64 + 144

√208

Answer:

4\sqrt{13}

Step-by-step explanation:

Calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, - 5)

d = \sqrt{(6-(-2))^2+(-5-7)^2}

   = \sqrt{6+2)^2+(-12)^2}

   = \sqrt{8^2+144}

   = \sqrt{64+144}

   = \sqrt{208}

   = \sqrt{16(13)}

   = 4\sqrt{13}

A frame of width a surrounds a 5 by 7 inch photograph. Find the expression that represents the area of the frame in terms of a.
Arada [10]
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35

minus original aera
which is 5 by 7 which is 35

4a²+24a+35-35=4a²+24a


3rd option I think, can't tell which is which
