What are the zeros of the quadratic function f(x) equals 6X squared +12 X -7
tamaranim1 [39]

The zeroes of the function will be \rm -1 \pm \dfrac{\sqrt{78}}{6}}

<h3>What is a Quadratic Function ?</h3>

A quadratic function is given by ax² +bx+c = f(x)

The given quadratic function is

f(x) = 6x² +12x - 7

The zeroes of the function will be given by

f(0) = 0

6x² +12x - 7 = 0

The zeroes are given by

\rm \dfrac {-b  \pm \sqrt{b^2 -4ac}}{2a}

here

a = 6

b = 12

c = -7

Therefore the zeroes of the function will be

\rm \dfrac {-12  \pm \sqrt{12^2 -4*6*(-7)}}{2 *6}

\rm \dfrac {-12  \pm \sqrt{312}}{12}

\rm -1 \pm \dfrac{\sqrt{78}}{6}}

Therefore these are the two zeroes of the function.

Help please, just number 3, thats all im asking, thanks.
Bezzdna [24]

The rectangle that has area 400 has width 10, so its length is 40.

A = LW; L = A/W = 400/10 = 40

The length is 10 + 0.2 = 10.2. The width is 10 + 2 = 12

The multiplication is 10.2 * 12

40.2 * 12 = 40 * 10 + 0.2 * 10 + 40 * 2 + 0.2 * 2

40.2 * 12 = 400 + 2 + 80 + 0.4

40.2 * 12 = 482.4
