Yeah, you’re right, I like to think that when the number is a decimal and I have to put it in scientific notation the exponent next to the 10 is negative and then when the number is a whole number and I have to change it to scientific notation then the exponent next to the ten is positive.
1. Always true. 1+1=2
2. Always true. 1+e is irrational.
3. Sometimes true. e + (-e) = 0 which is rational.
4. Always true. 1*1 = 1
5. Sometimes true. 0*e = 0 which is rational.
6. Sometimes true. Sqrt(2) * sqrt(2) = 2 which is rational.
The question asked for an example to support your answer, but none of the answers can be proven with just one example. The answers which are sometimes true need 2 examples to be proven, and the answers which are always true cannot be proven by example.
Answer:
Use your protractor to draw the lines
Step-by-step explanation:
You worked out the angles, so using the centre point as the middle and the line underneath France as your starter line, do 108° sector for Spain, then a 90° for Greece and a 12° for Others

Sorry I do t know the others
Haven’t gone over that
Hope this helps
