Answer:
Step-by-step explanation:
if f(x)=3x-1 and g(x)=2x+5 then
f(x)-g(x)=3x-1-(2x+5)
f(x)-g(x)=3x-1-2x-5
f(x)-g(x)=x-6
Im guessing that your teacher wants you to apply the fact that no matter what order your numbers are in when adding or multiplying your outcome will be the same. So one multiplication fact is 16*147=2352 . Also if you multiply a negative times a negative you will get a positive number so -147*-16=2352 .
I hope this helps a lil:)
Answer:14
Step-by-step explanation:
This is the concept of trigonometry, to solve for the value of the other length will be given cosine rule;
c^2=a^2+b^2-2ab cos C
substituting the values in our formula we get:
c^2=12^2+18^2-2*12*18*cos 60
c^2=144+324-432 cos60
c^2=252
hence
c=sqrt252
c=15.88m
thus the fixed length will be 15.88 m
