PEMDAS. First, use the distributive property with -3(2x) + -3(-4) to get -6x + 12. Remember the 9, so you get 9 - 6x + 12. Now add 9 and 12 to get 21 - 6x.
Answer: 97
Step-by-step explanation:
Answer:
8 m, 17 m and 22 m
Step-by-step explanation:
The first side is x
The second is 1 more than twice the first = 2x + 1
The third is 2 less than 3 times the first = 3x - 2
Sum the 3 sides and equate to 47
x + 2x + 1 + 3x - 2 = 47, that is
6x - 1 = 47 ( add 1 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Thus
side 1 = 8 m
side 2 = 2x + 1 = 2(8) + 1 = 16 + 1 = 17 m
side 3 = 3x - 2 = 3(8) - 2 = 24 - 2 = 22 m
