Answer: 
Step-by-step explanation:
So, it's x*x+x*-3+-4*x+3*-3
That simplifies to x^2 - 7x + 12

Answer:
A
Step-by-step explanation:
Remark
f and d are equal (and acute) because they are corresponding angles. 
82 and f are supplementary, so we can find f
Finding f
f + 82 = 180
f = 180 - 82
f = 82
Finding d
d = f
d = 82
