Answer:
− 8 x ^5 + 2 x ^2 + 7 x
Step-by-step explanation:
I couldn't see the last number but I believe it was a 5
i think its 18%
a, b, and d
w+2x=16 ⇒ w=16-2x
x+2w=14 x+2(16-2x)=14
x+32-4x=14
-3x=14-32
-3x=-18 /:(-3)
x=6
w=16-2x=16-2·6=16-12=4
2y+w=-6 ⇒ 2y+4=-6
2y=-6-4
2y=-10 /:2
y=-5
x=139
angles on a straight line add up to 180 degrees
