Write the equation for the quadratic function in the graph

Hoochie [10]

Answer:

${x}^{2} - 16 = 0 \: is \: the \: equation$

Step-by-step explanation:

$x = - 4 \\ or \: x = 4$

$(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket$

$x(x - 4) + 4(x - 4) = 0$

${x}^{2} - 4x + 4x - 16 = 0 \\ {x}^{2} - 16 = 0$

An equilateral triangle is a triangle that has three sides of the same length. the perimeter of an equilateral triangle is 48.6

aleksklad [387]

We know that a triangle has three sides, all the same length (its equilateral, after all)

The equation to find the length of each side is

Perimeter divided by 3

or in this case

48.6 divided by 3=16.2cm (don't forget the unit)

Hope that helps :)
