Answer:f(x)= -2(x-105)^2+18050
Step-by-step explanation: if you plug in 10 as x the answer would equal to zero. And then if you plug In 105 as x the answer would equal to 18050 proving the answer to be correct.
Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3). 3) Keep simplifying. The square root of a perfect square becomes just a number, without theradical<span> square root symbol.</span>

Answer:
Peggy is correct, their total bakes sale = $396.75
Step-by-step explanation:
Using estimation to help Peggy explain why Leslie reasoning is incorrect.
From the question we can see that:
First bake sale they made = $79.35
4 more bake sales making the same amount = 4 × $79.35
The total amount they would make from the bake sales =
$79.35 + (4 × $79.35)
= $396.75
Peggy was right. Leslie's reasoning was incorrect.
