Xelga [282]

$7\pi y^2\ represent\ the\ area\ of\ 7\ circles.\\\\Area\ of\ the\ circle:A_O=\pi r^2\ where\ r\ is\ a\ radius\ of\ the\ circle.\\\\In\ your\ example\ r=y\ therefore\ area\ of\ the\ one\ circle\ is\ equal:\\\\A_O=\pi y^2\\\\area\ of\ the\ 7\ circles\ is\ equal\ 7A_O=7\pi y^2$

I WILL GIVE BRAINLIEST AND THANKS SOLVE THE QUADRATIC EQUATION

laiz [17]

Answer:

x = -0.907, 2.57

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Since we are given <em>a</em> = 3, <em>b</em> = -5, and <em>c</em> = -7 from our quadratic, we simply use the Quadratic Formula:

Step 1: Plug in variables

$x=\frac{-(-5)+/-\sqrt{(-5)^2-4(3)(-7)} }{2(3)}$

Step 2: Solve

$x=\frac{5+/-\sqrt{25+ 84} }{6}$

$x=\frac{5+/-\sqrt{109} }{6}$

Step 3: Evaluate for decimals

You should get x = -0.906718 and 2.57338 as your answers.
