altogether there are 7 marbles in the bag.
put the marbles in fractions, so blue would be 3/7
and red would be 4/7. but becuase you need 2 of the same, you do
3/7 x 3/7 = 9/49
4/7 x 4/7 = 16/49
then add them togther
25/49
if you need it as a percentage, it is
51.020408163265%
Answer:
Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.
Step-by-step explanation:
Identify first the common difference of the arithmetic sequence by the following,
d = (a22 - a1) / 22 - 1
d = (-226 - 26) / 22 -1 = -12
Solving for the 31st term,
a31 = a1 + (n - 1)d
a 31 = 26 + (31 - 1)(-12)
a 31 = -334
Therefore, the answer is letter A. -334.
