To find the area you use the formula A = pr^2
So if the radius is 3y, substitute it in the r place.

A = p(3y)^2
A = 9y^2p

(p means pi)

Given that g(x)=3x²-5x+7 find the following: <br> g(-x)
AURORKA [14]
G(x) = 3x² - 5x + 7
g(-x) = -(3x² - 5x + 7)
g(-x) = -3x² + 5x - 7

This equation cannot be solved because of a few reasons,

1. This equation didn't show that it equals to 0.
2. Even if it equals to zero, square root of a negative number cannot be solved.
(I will show you what I mean)

-3x² + 5x - 7
is the same as
3x² - 5x + 7
by shifting the equation,

for example,
1 - 3 = -2
shifting other side
2 = -1 + 3

using 3x² - 5x + 7 to solve,

Solve\ using\ the\ formular\ \ \boxed{ x= { \frac{-b \pm \sqrt{b^2-4ac} }{2a} } }
a = 3
b = -5
c = 7
x= { \frac {-(-5) \pm \sqrt{ (-5)^2-4(3)(7) } }{2(3)} }
x= { \frac {5 \pm \sqrt{-59} }{6} }

∴This equation cannot be solved.

Y=2x/a+2b solve for a
Serga [27]

\text{Hello there!}\\\\\text{Solve for a:}\\\\y=\frac{2x}{a}+2b\\\\\text{Multiply both sides by a}\\\\ay=2x+2ab\\\\\text{Subtract both sides by 2ab}\\\\ay-2ab=2x\\\\\text{Factor out a}\\\\a(y-2b)=2x\\\\\text{Divide both sides by y-2b}\\\\a=\frac{2x}{y-2b}\\\\\boxed{a=\frac{2x}{y-2b}}
