Answer:
they will have 15.02 left over
Step-by-step explanation:
Alex:
21*.35=7.35
21-7.35= 13.65
13.65*.10=1.37
13.65+1.37=15.02
Lara:
21*.65=13.65
13.65*1.10=15.02

theres two numbers so i believe 2
Y equals 3x-3 is the answer
Answer:
Factor x²−6x−27 using the AC method.
(x−9)(x+3)=0
If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0.
x−9=0
x+3=0
Set x−9
equal to 0 and solve for x.
x=9
Set x+3 equal to 0 and solve for x.
x=−3
The final solution is all the values that make (x−9)(x+3)=0 true.
x=9,−3
