Answer:
x^2-6x
Step-by-step explanation:
Let's start by factoring the top, or numerator of the fraction.

Now, you can divide this by (x-1):

Division is multiplication by the reciprocal. The reciprocal is when you see what times your fraction equals 1.
Here's your answer. Just simplify now.
7/8 * 4/9= 28/72
Answer:
Sum angle of triangle BHD = 180°
36 + 39 + BHD = 180
BHD = 180 - 36 - 39
= 105°
BHD + x° = 180° (straight angle)
105° + x° = 180°
x = 180 - 105
= 75°
Hmmm, just follow what ur gut thinks ifthat make sense
