3. Mr. Miller has 5 girls and 6 boys in his class. Write a part-to-whole ratio to represent his class

A part to whole ratio is 5:11

Step-by-step explanation:

There are 5 girls which is a part and 11 which is 5 plus 6 and that is a whole

part a)

for extraneous solution

1 ⋅ sqrt(x+2) + 3 = 0

for non extraneous solution

1⋅ sqrt(x+2)  + 3 = 6

part b) solve each equation

1⋅sqrt(x+2)+3=0

x+sqrt(x+2)=−3

square both sides

(sqrt(x+2))^ 2 = (−3)^2

x+2=9

x=9−2

x=7

do you see why its extraneous
