Answer:
Step-by-step explanation:
Factor out 6
I assume you mean 6x^2+30x+36, because that makes far more sense
6(x^2+5x+6) = 6(x^2 + 2x +3x +6)
(To find that it is 2x and 3x: 2 +3 = 5, 2 * 3 = 6)
Factor by grouping:
6* x(x+2) +3(x+2) = 6(x+3)(x+2)
For binomials, it could be either (6x+18) (x+2) or (x+3) (6x+12), depending on where you multiply the 6.
Answer:
3 years
Step-by-step explanation:
let the number of years required be x
hence
42+x+44+x = 4(7+x+5+x+2+x)
86+2x = 4(14+3x)
86+2x = 56+12x
2x-12x = 56-86
-10x = -30
x = 3

(-1,5,0)
Step-by-step explanation:
The line goes straight up
Answer:
Step-by-step explanation: Part 1) The units rates are
A)
B)
C)
D)
Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction
Find the unit rate
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
Find the unit rate
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
Find the unit rate
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
Find the unit rate
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
The best buy is the size 48 1/4 oz
