Assuming that the actual question reads lines b and c are perpendicular to line d
we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)
So b is also parallel to line a
No the don't add up to one eighty I'm pretty sure if not tell me
It is 102.5. You made it kind of confusing at first by putting the divisor first in your question then putting your dividend, but I understand what you meant.
The correct answer is . . .
(75 widgets per hour)*(1 hour per 60 minutes)*(6 minutes)
(75)*(1/60)*(6)
75*(6/60)
75*(1/10)
<u><em>7.5 widgets per 6 minutes</em></u>
So what you do is evaluate g(2) then plug that value in for x in f(x)
g(2)=2^2-6(2)-7
g(2)=4-12-7
g(2)=-15
now
f(-15)=-15+8
f(-15)=-7
f(g(2)=-7
