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

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

let four consecutive whole numbers : n , n+1 , n+2 , n+3

the sum is : n + n+1 + n+2 + n+3 =4n+6

you can write 4n+6 to the form : 2(2n+3) means 2k ( k=2n+3)

so even number
