If you multiply 2.54 centimeters by 89 inches.

You get 226.06 Centimeters.

Your answer is 226.06 Centimeters.

Hope this Helps!

Find the zeros of y = x2 – 6x – 4 by completing the square.

katrin [286]

Answer:

The solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

Step-by-step explanation:

Given the function

$y\:=\:x^2\:-\:6x\:-\:4$

substitute y = 0 in the equation to determine the zeros

$0\:=\:x^2\:-\:6x\:-\:4$

Switch sides

$x^2-6x-4=0$

Add 4 to both sides

$x^2-6x-4+4=0+4$

Simplify

$x^2-6x=4$

Rewrite in the form (x+a)² = b

But, in order to rewrite in the form x²+2ax+a²

Solve for 'a'

2ax = -6x

a = -3

so add a² = (-3)² to both sides

$x^2-6x+\left(-3\right)^2=4+\left(-3\right)^2$

$x^2-6x+\left(-3\right)^2=13$

Apply perfect square formula: (a-b)² = a²-2ab+b²

$\left(x-3\right)^2=13$

$\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}$

solve

$x-3=\sqrt{13}$

Add 3 to both sides

$x-3+3=\sqrt{13}+3$

Simplify

$x=\sqrt{13}+3$

now solving

$x-3=-\sqrt{13}$

Add 3 to both sides

$x-3+3=-\sqrt{13}+3$

Simplify

$x=-\sqrt{13}+3$

Thus, the solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

Please Answer ASAP, Thx! 5x -2y=17 and 4x - 3y= 8

iVinArrow [24]

5x - 2y = 17

4x - 3y = 8

Try to change one of the equations to isolate a variable, so you can use the new equation and substitute it into the other equation.

5x - 2y = 17

-2y = 17 - 5x

y = -17/2 + 5/2x

Now plug this into the second equation

4x - 3(-17/2 + 5/2x) = 8

4x + 51/2 - 15/2x = 8

8/2x - 15/2x = 16/2 - 51/2

-7/2x = -35/2

x = 5

Plug this into either equation to find y

4x - 3y = 8

4(5) - 3y = 8

20 - 3y = 8

-3y = -12

y = 4

x = 5, y = 4
