Answer:
1.5n
Step-by-step explanation:
The distributive property can be used to simplify expressions like this (collect terms).
= n(4 -1 +.5 -2)
= n(3 +.5 -2)
= n(3.5 -2)
= n(1.5)
= 1.5n
_____
Of course, you can do the addition in any convenient way. Some like to add all the positive and negative terms, then find the difference.
= n((4 +.5) -(1 +2)) = n(4.5 -3) = 1.5n
D = 117
because angle 63 = angle 37+a because they are vertical angles,
therefore angle angle 37+a= angle b because they are corresponding angles
so if angle b=63 then angle d=117, so that together they equal 180, a supplementary angle.
