1)
y=6
x^2+6^2=25
x^2=25-36
x^2= -9
x^2=i^2.9
x=3i there's no real solution
2)
x^2+(2x-2)^2=25
x^2+4x^2-8x+4=25
5x^2-8x=21
5x^2-8x-21=0
5x +7
x -3
(5x+7)(x-3)=0
x= -7/5
x=3

Answer to your question is A
Based on the times that the machine produces cookies that have the optimal amount of chips, the proportion produced daily with the optimal number of chips is 62.5% or 0.625.
<h3>What is the proportion of cookies with optimal chocolate chips?</h3>
This can be found by the formula:
= (Hours that optimal cookies are produced) / Hours that the machine runs per day
5:30 am is the same as 5.5 hours because 30 minutes is half an hour.
1:30 pm is also the same as 13.5 hours by the above rule and in 24 hour notation.
Proportion of optimal cookies is therefore:
= (11 am - 6am) / (13.5 - 5.5)
= 5 / 8
= 0.625
= 62.5%
