I believe it is C, there is a geometric law that states that the opposite angles across a line with both going into parallel lines will be the same angle. Rather confusing but a video online would likely explain it better than anyone could here.
If you use PEMDAS: Parentheses, Exponents, Multiply, Divide, Add, Subtract for order of operations your answer will be 277
9x27+2x31-28
243+62-28
305-28=277
Answer:
<h2><em><u>
a) is correct</u></em></h2>
3n + 5
1. Substitute the numbers
3(5) + 5 = 15 + 5 = <em><u>20</u></em>
2. Substitute the second number
3(6) + 5 = 18 + 5 = <em><u>23</u></em>
<h2><u><em>
b) Numbers are 8 and 16.</em></u></h2>
This is because I realized I got the number of 4 last because I did 1*2 = 2.
Then I did 2*2 = 4.
So you have to multiply by two to get the next number. Or you can put it to the 4th or 5th exponent of 2.
1. 1
2. 1*2 = 2
3. 2*2 = 4
<h2><em><u>
4. 4*2 = 8</u></em></h2><h2><em><u>
5. 8*2 = 16</u></em></h2>
