F(x) = input the x
3x+2
multiply it by 3 and add 2
3*x+2=
3*5+2=
15+2 =
17
or if you meant 2x:
it would be the same just do:
3+2x
3+2*5
3+10
13
Answer:
Consecutive odd integers are 19 , 21 & 23
Step-by-step explanation:
Let the first 3 consecutive odd intergers be x , (x + 2) and (x + 4).
According to the question,


Eliminating 2x from both the sides,



So, the consecutive odd integers are = 19 , 21 & 23.
Subtract 9 twice.
24-9-9 = 6
Half of 6 is 3, so 3 is the width since adding it twice and adding the length twice gives perimeter.
Answer:
Step-by-step explanation:
Two faces are 6” by 9”. Two faces are 6” by 2”. Two faces are 9” by 2”.
Surface are = 2*6*9 + 2*6*2 + 2*9*2 = 108 + 24 + 36 = 168 square inches
