To factor this collect the like terms..2y would go with -7y to make -5y etc. Then factor the expression by factoring out 9 Your final answer should be 9(1-y+x^2)
If you need to simplify this calculate the sum or difference between numbers (3-1+7=9)
Your final answer for this should be 9-9y+9x^2
Hope this helps!
I believe it might be A or C. Not really sure
It's either 8 cm or 1 m....i personally think 8 cm is more accurate but, 1 m is still an acceptable answer
Step-by-step explanation:
3n + 6( -8n + 9)
= 3n - 48n + 54
= - 45n + 54
Hope it will help
D is the one that is decreasing
