Answer:
In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate, x, is x^2 − 4x + 7.
Answer:
x=3
Step-by-step explanation:
4x−2(x−4)=−3+4x+5
4x+(−2)(x)+(−2)(−4)=−3+4x+5
4x+−2x+8=−3+4x+5
(4x+−2x)+(8)=(4x)+(−3+5)
2x+8=4x+2
2x+8−4x=4x+2−4x
−2x+8=2
−2x+8−8=2−8
−2x=−6
−2x
/−2
=

Answer:
A. 30000
B. 12000
Step-by-step explanation:
Find out how much spectators leave in 1 minute.
1 second = 5
1 minute = 5 x 60 = 300 (60 seconds)
20 minutes = 300 x 20 = 6000
Since there were only 80% of the full capacity of spectators and after minutes it became 60%...
80% - 60% = 20%
20% = 6000
1% = 6000 ÷ 20 = 300
100% = 300 x 100 = 30000
1 minute = 300 spectators leaving
1 hour = 300 x 60 = 18000 (60 minutes)
30000 - 18000 = 12000
Answer: Tammy's sample may not be vaild because she surveyed the students only from her class and it is likely that other classes might not like the subject maths. She might get the accurate results by surveying a larger number of people in the school instead of just her class.
