The best estimate would be in the two thousands
The actual answer is 2023
9x + 6 + 2(5x-3) + 5y +14
9x + 6 + 10x - 6 + 5y +14
19x + 5y + 14
19x = -5y -14
x = -5y/19 - 14/19
Answer:
-0.6n+0.2p
Step-by-step explanation:
2.8n-0.9p-3.4n+1.1p
You can only add the numbers with the same variables (n,p)
2.8n-3.4n-0.9p+1.1p
= -0.6n+0.2p
60 I think, because it’s base times height divided by two
