Answer:
x =2
Option D is correct !!!
Step-by-step explanation:
By Pythagoras theorem we can solve this
we know that:




Answer:
9x2 +42x + 24 <u>is</u> (x + 4) (9x + 6)
9x2 + 30x + 24 <u>is</u> (3x + 6) (3x + 4)
9x2 + 58x + 24 <u>is</u> (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)
Y=mx+b
Slope is m
Y intercept is b
So it's-4
The answer is y-x because there are y seats and x people leave and the key word is leave. When there is words like leave or less those give you hints that mean you are subtracting.
