Answer:
1.  16
2.  -4
Step-by-step explanation:
First factor the expression
lim x→1  (x^3 + 5x^2 + 3x-9)/(x-1)
lim x→1  (x-1) (x+3)^2/(x-1)
Canceling the x-1  in the top and bottom
lim x→1   (x+3)^2
Let x=1
lim x→1   (1+3)^2 = 4^2 = 16
2.  lim x→0 (x^2 -6x+8) /(x-2)          
First factor the expression
     lim x→0 (x-4) (x-2) /(x-2)        
Canceling the x-2  in the top and bottom
 lim x→0 (x-4) 
Let x=0
lim x→0   (0-4) = -4
Filling in the table
x     -.1      -.01       -.001     .001     .01     .1
f(x) -4.1  -4.01    -4.001   -3.999   -3.99  -3.9
 
        
                    
             
        
        
        
The original cost is $3.00.
Hope this helps and if someone else comments put mine brainliest.

Answer:
Maggie is 13 years old. 
Step-by-step explanation:
1M + 1B = 62 
rearrange to get:
1B = 62 - 1M
4M - 3 = 1B
substitute B with 62 - 1M so there is only one variable. this gives:
4M - 3 = 62 - 1M
Get all the variables on one side:
4M + 1M - 3 = 62
Get all non variables on the other side:
4M + 1M = 62 + 3
simplify:
5M = 65
Divide both sides by 5 to get the M by itself:
M = 13. 
BONUS:
M + B = 62
B = 49
So her brother is 49 years old.
