Answer:
the terms are 400n , 62n 120 and 8n
the number of coefficients is 3
equa expression is 346n+120
Step-by-step explanation:1
Combining like terms 400n400n and -62n−62n
338n+120+8n
338n+120+8n
2 Combining like terms 338n338n and 8n8n
346n+120
346n+120
For the rest of them i just counted.
the square root of 42 is not a rational number, it is an irrational number
Answer:
the answer is 1.453
Step-by-step explanation:
i am not sure about the answer but here are my steps. first he says in the 1990s there was a deforestation rate of about 0.48%per year. and 1 is the rate of land that is shrinking. this means that if Brazil had a forest of area x then
x(0.48%)=1 therefore x=2.083
lets use that in this equation
the area left (the final answer) 2.083(0.48)^35= 1.453
(i asked about the unit its measured with because if it is measured by thousands of squared meters or kilometers just big unit measured to be exact my answer would be correct)
