Answer:-4y^3-12y^2-7x
Step-by-step explanation:if you collect the liked terms it will add up to get that
Because GH bisects FGI, FGH=HGI
2x+1=3x-9
x=10°
so the measure of HGI is 21°
Answer:
II. Angle C cannot be a right angle.
III. Angle C could be less than 45 degrees.
Answer:
9. a) 180 - (55+90) = a
b) a=35 degrees
10. a) 2w + 3w + 40 = 180
b) w=28
c) 2w=56 3w=84
