Answer:
In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7
Step-by-step explanation:
The sum of -3 and a number equal to -91 is -88
You can eliminate 81 because we know 
The dot is on approximately 9.32 (my estimate) so I would square that number:
(9.32)² = 86.8624 so if you round this you get 87
This means you should do 240*3/8 which is 90. so 90 times 240=21600
the answer is 216000km^2
Answer:
the answer is one line is increased by 1, and the other increased by 6
hope this helped :))
