Answer:
3f -9g +7
Step-by-step explanation:
(–3f – 4g + 9) – (2 – 6f + 5g)
Distribute the minus sign
(–3f – 4g + 9) – 2 + 6f - 5g
I like to line them up vertically
–3f – 4g + 9
+ 6f - 5g -2

Step-by-step explanation:
Fist we find the legnth of the diagonal
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
c=5
now the other diagonal
11^2+5^2=c^2
121+25=c^2
146=c^2
sqrt both sides12.083
closest is B
