Answer:
There is no solution :/
Step-by-step explanation:
81x^2+180x+100=81x
Step 1: Subtract 81x from both sides.
81x^2+180x+100−81x=81x−81x
81x^2+99x+100=0
For this equation: a=81, b=99, c=100
Step 2: Use quadratic formula with a=81, b=99, c=100.
x= −b±√b2−4ac/ 2a
x= −(99)±√(99)2−4(81)(100) / 2(81)
x= −99±√−22599/162
So you see... no solution
Hope this helps!
Answer: x=9
(5x+7)
5 x 9 = 45
45 + 7 = 52

The area of a circle is A= pi × r² (r being the radius)
The radius is half the diamter so the radius would be 6
Plug 6 into the equation for the radius
A = pi × 6²
A = pi ×36
A= 18.85
24 is correct answer
hope it helped you:)
