Answer:
-4b^3 + b^2
Step-by-step explanation:
17.5 = x
Step-by-step explanation:
1st you add 85 and 55 since those to angles are congruent (means similar) to 8x
2nd you get 140 after adding then
3rd since the angles are congruent you just divide the 140 by 8 to get the value of x
Answer:
D
Step-by-step explanation:
For lines to be parallel they must have the same slope. If:
y=mx+b
For any line to be parallel to the above it must also have the same value for m in that line.
Here a = 2, b = -2, c = -1
b^2-4ac = (-2)^2 - 4(2)(-1)
= 4 +8
= 12
