The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.

Area of Square + 4*Area of Triangle = SA

Area of Square:
2^2=4

Area of Triangle:
0.5*2*3=3

SA=4+4*3
SA=16 meters squared

Use the quadratic formula to solve the equation. <br> x ^2 – 7 x –6 = 0<br> (Show work)
Vika [28.1K]

Given a quadratic equation

ax^2+bx+c=0

the quadratic formula states that the solutions are

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Plug your values to get

x_{1,2}=\dfrac{-(-7)\pm\sqrt{(-7)^2-4\cdot 1 \cdot (-6)}}{2\cdot 1}

Which evaluates to

\dfrac{-(-7)\pm\sqrt{(-7)^2-4\cdot 1 \cdot (-6)}}{2\cdot 1} = \dfrac{7\pm\sqrt{73}}{2}

So, the two solutions are

x_1 = \dfrac{7+\sqrt{73}}{2},\quad x_2 = \dfrac{7-\sqrt{73}}{2}
