Answer:
1B , 2B , 3 Output = 2*input + 1
Step-by-step explanation:
1. given (3n + 5) * 2
first do the operation between brackets.
n=5 so (3*5) =15 which gives (15 + 5)=20
now finish with the operation after the brackets, which is multiply by 2. 20*2 = 40, which is answer B.
2. 3x means 3*x which means in words: 3 times the number, which is answer A.
3. From the tabe you can see that if you just multiply the input by 2, you are almost at the output. If you add 1 then it is perfect..So you get Output = 2*input + 1
Answer:
ntersecting lines DA and CE.
To find:
Each pair of adjacent angles and vertical angles.
Solution:
Adjacent angles are in the same straight line.
Pair of adjacent angles:
(1) ∠EBD and ∠DBC
(2) ∠DBC and ∠CBA
(3) ∠CBA and ∠ABE
(4) ∠ABE and ∠EBD
Vertical angles are opposite angles in the same vertex.
Pair of vertical angles:
(1) ∠EBD and ∠CBA
(2) ∠DBC and ∠EBA
The short answer is: when their fractions add up to full integers.
For examples, two halves make up a whole, or

so the mixed numbers with those will add up to full integers:

but if they don't add up to an interger, the whole sum won't be an integer:
Answer:
rational, integer
