Answer:
4.) 12
Step-by-step explanation:

Answer: -96r + 13
1. distribute 8x2 - 8x12r
-3+8(2-12r)
-3+16-96r
2. add constants -3+16
-3+16-96r
13-96r
3. standard form
-96r + 13
A) a is complementary to 70° so it is 20°
b) a and b are complementary so b is 70°
c) c is complementary to b so it is 20°
d) d is complementary top c so it is 70°
e) e is a linear pair with d so it is 110°
3) supplements add to 180 so 180-122=56
4) p and q are supplementary so q=180-90=90
5) a and t are complementary sup both are less than 90. that means the supplement out both is >90 and thus obtuse
6) acute
