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
Answer:
-9 is the largest integer with in [-12, -9]
Step-by-step explanation:
the list of numbers in that interval is -12, -11, -10, -9. out of those four numbers the largest is -9.
* using brackets [ ] means it includes the outside numbers given
ex. [-12, -9] is -12, -11, -10, -9
but using prenthesis ( ) does not include the outside numbers
ex. (-12, -9) is -11, -10
The answer is -91 because f(x) is 7 and g(x) is -13 and so 7(-13) is -91
