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!

9(y+6)+2y(y+3)/((y+3)(y+6))= optin b
please mark me as brainlest
For this qestion u will do step b
$42.90
to find how much money selling the large necklaces multiply the amount and how many were sold
5.40*7
$37.80
add the money from the one small necklace that was sold
37.80+5.10
an = 63(-1/3)^(n-1)
This is a geometric sequence with first term 63 and common ratio -1/3.
The equation for the nth term is
an = 63(-1/3)^(n-1).
