Answer:
f(2b) = 4b^2 +4b +1
Step-by-step explanation:
Put 2b where x is and simplify.
f(2b) = (2b)^2 +2(2b) +1
f(2b) = 4b^2 +4b + 1

Answer:
number of yellow marbles=62.
Step-by-step explanation:
It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.
Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.
Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒66=6x
⇒x=11
Therefore, numberof blue marbles=x=11 and
number of yellow marbles=5x+7=5(11)+7=55+7=62.
