Answer:
6x -3x^4
Step-by-step explanation:
Eliminate parentheses. Since the multiplying coefficient is +1, the parentheses can simply be dropped:
= 3x +2x^4 +3x -5x^4
Add like terms (ones with the same exponent on the variable).
= 3x +3x +2x^4 -5x^4 . . . . . . . group like terms together
= (3+3)x +(2-5)x^4
= 6x -3x^4
Answer:
That is true!

Answer:
0.6765 = 67.65%
Step-by-step explanation:
This situation can be treated as a binomial model with probability of success (dented can) of p = 0.05.
In 22 random trials, the probability of at least one success is determined by:

The probability that Karen has bought at least one dented can is 0.6765 or 67.65%.
