B is the answer because 1+3 is 4 4+5 is 9 9+7 is 16 16+9 is 25 25+11 is 36+13 is 49 and so on
9514 1404 393
Answer:
(d) 9
Step-by-step explanation:
The relation you're supposed to apply here is ...
an exterior angle of a triangle is equal to the sum of the remote interior angles.
__
The exterior angle is 17x+7, and it is equal to the sum of the two marked angles inside the triangle.
17x +7 = 13x +3 +40
4x = 36 . . . . . . . . . . . . . subtract 13x+7 from both sides
x = 9 . . . . . . . . . divide both sides by 4
18y + 9 = -12 + 18y
9=-12
I hope that’s right... I haven’t done this in ages
Looking at the choices i believe you need a g in your question. If it is 4g+2
Then you factor out at 2 to get 2(2g+1) choice a
If it 4+2g then you also factor out a 2 but this time get 2(2+g) choice b
Depending on what the question actually is those would be the answers
The next number in the sequence is 34. as you add the previous two numbers to get the next.
