You will have to take 3x common from both terms and your ans should look like this,
3x(9x^2-4)
Answer: D) vertical angles theorem, alternate interior angles theorem
Angle 5 = Angle 6 by the alternate interior angles theorem
Angle 5 = angle 4 by the vertical angles theorem
By the transitive property, we can then say angle 4 = angle 6. These angles are also corresponding angles.
We won't use the angle addition theorem or the right angles theorem.
6/10 and 13/20, sorry i would explain this but its late, cheers.
Hope this Helps.
for a line in the form of y=mx+b, the slope is m and he y intercept is b.
y= -3/4x + 3/2m = -3/4, b=3/2
The answer is six and two out of seven or 6 and two sevenths
