Base :
A = s^2
A = 10 ^ 2
A = 100 sq in

sides :
A = 4 ((1/2)(4)(10))
A = 4 (2(10))
A = 4 (20)
A = 80 sq in

total area = 180 sq in

<u>Let's take this problem step by step:</u>

<u>To find the ordered pair of the system:</u>

⇒ must set both equations equal to each other

    ⇒ and solve for 'x'

<u>Let's solve:</u>

 x^2-2x+3=-2x+19\\x^2-2x+2x+3-19=0\\x^2-16=0\\(x+4)(x-4)=0

<u>Let's find the x-values:</u>

   (x-4)=0\\x=4\\\\(x+4)=0\\x=-4

<u>Let's find f(x)'s value for each 'x':</u>

 x=4\\f(4)=-2(4)+19=-8+19=11\\\\x=-4\\f(-4)=-2(-4)+19=8+19=27

<u>Answer: (4, 11), (-4,27)</u>

Hope that helps!
