5x^2-2x=2<br>help plsmmm

Answer:

Presumably you're solving for x here? Without further information we'll assume that.

With that in mind, x is approximately equal to 0.86 and -0.46

Step-by-step explanation:

Let's start by putting it in the usual ax² + bx + c format.

$5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\$

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

$25x^2 - 10x - 10 = 0\\$

Now we'll add 11 to both sides:

$25x^2 - 10x + 1 = 11\\$

Which makes the left side a perfect square:

$(5x - 1)^2 = 11$

And now we can solve for x:

$(5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}$

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.

That gives us two answers:

$x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86$ $x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46$

Can someone please help!!!

It is simple, each y=3x so, lets just say that you have 8y, that would be equal to 24x. In other words, just multiply the number of y's, by 3

Let one length be x and the other be y

x + x + y + y = 440
2x + 2y = 440

Divide by 2 through ...
x + y = 220
y = 220 - x

Area = xy
Area = x(220 -x) = 220x - $x^{2}$

Given that that max length of x will be -b/2a
a = -1 b = 220
x = $\frac{-220}{-2}$ = 110

x = 110
y = 220 - 110 = 110

Therefore max area = 110 x 110 = 12100 square yards
